| Primary Identifier | IPR005175 | Type | Domain |
| Short Name | PPC_dom |
| description | The Plants and Prokaryotes Conserved (PPC) domain contains a hydrophobicregion in the C-terminal, and in the case of plants, is often found in severalproteins with the AT-hook motif. Proteins with PPC domains are found inBacteria, Archaea and the plant kingdom [, ].The PPC domain has a single α-helix packed against an antiparallel beta-sheet, which is formed by five β-strands. Three conserved histidine residues appear to form a zinc-binding site, and the domain has been observed to form homotrimers. The domain co-occurs with a thioredoxin-like domain in uncharacterized cyanobacterial proteins []. |
