Type 1 glutamine amidotransferase (GATase1)-like domain found in a subgroup of proteins similar to PfpI from Pyrococcus furiosus
Type 1 glutamine amidotransferase (GATase1)-like domain found in a subgroup of proteins similar to PfpI from Pyrococcus furiosus. PfpI is an ATP-independent intracellular proteases which may hydrolyze small peptides to provide a nutritional source. Only Cys of the catalytic triad typical of GATase1 domains is conserved in this group. This Cys residue is found in the sharp turn between a beta strand and an alpha helix termed the nucleophile elbow.
