Type 1 glutamine amidotransferase (GATase1)-like domain found in zebrafish ES1
Type 1 glutamine amidotransferase (GATase1)-like domain found in zebrafish ES1. This group includes, proteins similar to ES1, Escherichia coli enhancing lycopene biosynthesis protein 2, Azospirillum brasilense iaaC and, human HES1. The catalytic triad typical of GATase1domains is not conserved in this GATase1-like domain. However, in common with GATase1domains a reactive cys residue is found in the sharp turn between a beta strand and an alpha helix termed the nucleophile elbow. Zebrafish ES1 is expressed specifically in adult photoreceptor cells and appears to be a cytoplasmic protein. A. brasilense iaaC is involved in controlling IAA biosynthesis.
