Protein
dTDP-3-amino-3,6-dideoxy-alpha-D-glucopyranose N,N-dimethyltransferase
Organism
Streptomyces fradiae
Function
S-adenosyl-L-methionine-dependent methyltransferase involved in the biosynthesis of mycaminose, an essential structural component of the macrolide antibiotic tylosin. Involved in the last step in mycaminose biosynthesis by mediating dimethylation of the hexose C-3' amino group.
Similarity
Belongs to the methyltransferase TylM1/DesVI family.
