Type 1 glutamine amidotransferase (GATase1)-like domain found in Saccharomyces cerevisiae Ydr533c protein
Type 1 glutamine amidotransferase (GATase1)-like domain found in Saccharomyces cerevisiae Ydr533c protein. This group includes proteins similar to S. cerevisiae Ydr533c. Ydr533c is upregulated in response to various stress conditions along with the heat shock family. The catalytic triad typical of GATase1domains is not conserved in this GATase1-like domain. However, in common with a typical GATase1domain, a reactive Cys residue is found in the sharp turn between a beta strand and an alpha helix termed the nucleophile elbow. This Cys together with a different His and Glu residue form a different catalytic triad from the typical GATase1domain. Ydr533c protein is a homodimer.
