The members of this family are probably all pyridoxal-phosphate-dependent aminotransferase enzymes with a variety of molecular functions. The family includes StsA Swiss:P72454, StsC Swiss:P77952 and StsS [1]. The aminotransferase activity was demonstrated for purified StsC protein as the L-glutamine:scyllo-inosose aminotransferase EC:2.6.1.50, which catalyses the first amino transfer in the biosynthesis of the streptidine subunit of streptomycin [1].

This entry represents the N-terminal domain of NtdA, which is not found in other aminotransferases and consists of two-stranded parallel beta-sheet flanked by two alpha-helices [1]. This domain may be involved in protein-protein interactions. NtdA is a sugar aminotransferase involved in the biosynthesis of kanosamine.	Domain
