Description: This entry represents phytoene desaturase (PDS) from plants and cyanobacteria (blue-green algae). It is an essential carotenoid biosynthetic enzyme. It converts phytoene into zeta-carotene via the intermediary of phytofluene by the symmetrical introduction of two double bonds at the C-11 and C-11' positions of phytoene with a concomitant isomerization of two neighbouring double bonds at the C9 and C9' positions from trans to cis [, ].This entry does not include plant chloroplast transit peptides and the entry does not contain zeta-carotene desaturase, which is a closely related family in the same pathway.

Title: Structure of human C8 protein provides mechanistic insight into membrane pore formation by complement.
Volume: 286
Issue: 20
Pages: 17585-92
Protein Domain
Type: Domain
Description: This domain is found in complement component proteins, complement component factor 1 and agrin. Complement components C5b, C6, C7 C8 and C9 are the constituents of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells. Its assembly is initiated by protelytic cleavage of C5 into C5a and C5b. C5b binds sequentially C6, C7, C8 and multiple copies of the pore-forming subunit C9. Factor I is responsible for cleaving alpha chains of C4B and C3B in the presence of the cofactors C4-binding protein and factor H respectively. Agrin is a component of the basal lamina that causes the aggregation of acetylcholine receptors and acetylcholine-esterase on the surface of muscle fibres of the neuromuscular junction.
Protein Domain
Type: Family
Description: This entry represents the alpha chain of complement component C8. C8 is a complex of three chains, alpha, beta and gamma []. C8 is a component of the membrane attack complex (MAC) which forms pores in the membranes of cells of invading organisms. MAC forms when C5 is cleaved into C5a and C5b, and C5b binds sequentially C6, C7, C8 and multiple copies of the pore-forming subunit C9 [, ]. C8 alpha is synthesized as a precursor and activation occurs by cleavage at paired basic residues by kallikrein-related peptidase 4 []. The tertiary structure of C8 alpha has been solved and shows the following domains (N- to C-terminal): first TSP type-1, LDL-receptor class A, MACPF, EGF-like, and second TSP type-1 []. This domain architecture is shared with the beta chain of C8.
Protein Domain
Type: Family
Description: This entry represents complement component C7, a subunit of the membrane attack complex (MAC) which forms pores in the membranes of cells of invading organisms. C7 anchors the MAC to the membrane. MAC forms when C5 is cleaved into C5a and C5b, and C5b binds sequentially C6, C7, C8 and multiple copies of the pore-forming subunit C9 []. The structure of C7 has been solved and C7 contains a several domains, which from N to C terminus are: TSP type-1, LDL-receptor class A, MACPF, EGF-like, another TSP type-1 and two sushi domains []. Variants of C7 are associated with immunodeficiency diseases and susceptibility to infection such as meningococcal disease caused by Neisseria meningitidis [].

Protein Domain
Type: Conserved_site
Description: The membrane attack complex/perforin (MACPF) domain is conserved in bacteria, fungi, mammals and plants. It was originally identified and named as being common to five complement components (C6, C7, C8-alpha, C8-beta, and C9) and perforin. These molecules perform critical functions in innate and adaptive immunity. The MAC family proteins and perforin are known to participate in lytic pore formation. In response to pathogen infection, a sequential and highly specific interaction between the constituent elements occurs to form transmembrane channels which are known as the membrane-attack complex (MAC).Only a few other MACPF proteins have been characterised and several are thought to form pores for invasion or protection [, , ]. Examples are proteins from malarial parasites [], the cytolytic toxins from sea anemones [], and proteins that provide plant immunity [, ]. Functionally uncharacterised MACPF proteins are also evident in pathogenic bacteria such as Chlamydia spp []and Photorhabdus luminescens (Xenorhabdus luminescens) [].The MACPF domain is commonly found to be associated with other N- and C-terminal domains, such as TSP1 (see ), LDLRA (see ), EGF-like (see ),Sushi/CCP/SCR (see ), FIMAC or C2 (see ). They probably control or target MACPF function [, ]. The MACPF domain oligomerizes, undergoes conformational change, and is required for lytic activity.The MACPF domain consists of a central kinked four-stranded antiparallel beta sheet surrounded by alpha helices and beta strands, forming two structural segments. Overall, the MACPF domain hasa thin L-shaped appearance. MACPF domains exhibit limited sequence similarity but contain a signature [YW]-G-[TS]-H-[FY]-x(6)-G-G motif [, , ].Some proteins known to contain a MACPF domain are listed below:Vertebrate complement proteins C6 to C9. Complement factors C6 to C9 assemble to form a scaffold, the membrane attack complex (MAC), that permits C9 polymerisation into pores that lyse Gram-negative pathogens [, ].Vertebrate perforin. It is delivered by natural killer cells and cytotoxic T lymphocytes and forms oligomeric pores (12 to 18 monomers) in the plasma membrane of either virus-infected or transformed cells.Arabidopsis thaliana (Mouse-ear cress) constitutively activated cell death 1 (CAD1) protein. It is likely to act as a mediator that recognises plant signals for pathogen infection [].Arabidopsis thaliana (Mouse-ear cress) necrotic spotted lesions 1 (NSL1) protein [].Venomous sea anemone Phyllodiscus semoni (Night anemone) toxins PsTX-60A and PsTX-60B [].Venomous sea anemone Actineria villosa (Okinawan sea anemone) toxin AvTX-60A [].Plasmodium sporozoite microneme protein essential for cell traversal 2 (SPECT2). It is essential for the membrane-wounding activity of the sporozoite and is involved in its traversal of the sinusoidal cell layer prior to hepatocyte-infection [].P. luminescens Plu-MACPF. Although nonlytic, it was shown to bind to cell membranes [].Chlamydial putative uncharacterised protein CT153 [].

Functionally uncharacterised MACPF proteins are also evident in pathogenic bacteria such as Chlamydia spp []and Photorhabdus luminescens (Xenorhabdus luminescens) [].The MACPF domain is commonly found to be associated with other N- and C-terminal domains, such as TSP1 (see ), LDLRA (see ), EGF-like (see ),Sushi/CCP/SCR (see ), FIMAC or C2 (see ). They probably control or target MACPF function [, ]. The MACPF domain oligomerizes, undergoes conformational change, and is required for lytic activity.The MACPF domain consists of a central kinked four-stranded antiparallel beta sheet surrounded by alpha helices and beta strands, forming two structural segments. Overall, the MACPF domain has a thin L-shaped appearance. MACPF domainsexhibit limited sequence similarity but contain a signature [YW]-G-[TS]-H-[FY]-x(6)-G-G motif [, , ].Some proteins known to contain a MACPF domain are listed below:Vertebrate complement proteins C6 to C9. Complement factors C6 to C9 assemble to form a scaffold, the membrane attack complex (MAC), that permits C9 polymerisation into pores that lyse Gram-negative pathogens [, ].Vertebrate perforin. It is delivered by natural killer cells and cytotoxic T lymphocytes and forms oligomeric pores (12 to 18 monomers) in the plasma membrane of either virus-infected or transformed cells.Arabidopsis thaliana (Mouse-ear cress) constitutively activated cell death 1 (CAD1) protein. It is likely to act as a mediator that recognises plant signals for pathogen infection [].Arabidopsis thaliana (Mouse-ear cress) necrotic spotted lesions 1 (NSL1) protein [].Venomous sea anemone Phyllodiscus semoni (Night anemone) toxins PsTX-60A and PsTX-60B [].Venomous sea anemone Actineria villosa (Okinawan sea anemone) toxin AvTX-60A [].Plasmodium sporozoite microneme protein essential for cell traversal 2 (SPECT2). It is essential for the membrane-wounding activity of the sporozoite and is involved in its traversal of the sinusoidal cell layer prior to hepatocyte-infection [].P. luminescens Plu-MACPF. Although nonlytic, it was shown to bind to cell membranes [].Chlamydial putative uncharacterised protein CT153 [].
