Primary Identifier | IPR002791 | Type | Domain |
Short Name | ARMT1-like_metal-bd |
description | This domain is found in Damage-control phosphatases ARMT1, YMR027W from S. cerevisiae () and At2g17340 from Arabidopsis thaliana, and it is also found at the C-terminal portion of eukaryotic pantothenate kinases [, ]. Despite the characterization of ARMT1 as a carboxyl methyltransferase, a second study suggests that these proteins are hydrolases whose function is to limit potentially harmful buildups of phosphometabolites []. They are metal-dependent phosphatases involved in metabolic damage-control processes termed "damage pre-emption"or "housecleaning". Crystal structure of damage-control phosphatase At2g17340 revealed a novel protein fold and several conserved residues coordinating a metal ion (probably Mg2) with high degree of conservation suggesting that the metal-binding site is central for the function of this domain []. |
