Type 1 glutamine amidotransferase (GATase1)-like domain found in proteins similar to Saccharomyces cerevisiae biotin-apoprotein ligase (ScBLP)
Type 1 glutamine amidotransferase (GATase1)-like domain found in proteins similar to Saccharomyces cerevisiae biotin-apoprotein ligase (ScBLP). Biotin-apoprotein ligase modifies proteins by covalently attaching biotin. ScBLP is known to biotinylate acety-CoA carboxylase and pyruvate carboxylase. The catalytic triad typical of GATase1 domains is not conserved in this GATase1-like domain. However, the Cys residue found in the sharp turn between a beta strand and an alpha helix termed the nucleophile elbow in a typical GATase1 domain is conserved.
