strB2

Putative inosamine-phosphate amidinotransferase 2

349 amino acids

It is not obvious if strB2 participates in streptomycin biosynthesis as an inosamine-phosphate amidinotransferase. Attempt to measure its activity have failed and the nucleophilic cysteine which is the key residue for amidine transfer is not conserved but replaced by a glycine residue.

Belongs to the amidinotransferase family.

strB2

Putative inosamine-phosphate amidinotransferase 2

319 amino acids

It is not obvious if strB2 participates in streptomycin biosynthesis as an inosamine-phosphate amidinotransferase. The nucleophilic cysteine which is the key residue for amidine transfer is not conserved but replaced by an arginine residue.

Belongs to the amidinotransferase family.
