Protein
Probable 1,4-alpha-glucan branching enzyme Rv3031
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Function
Catalyzes the formation of branch points in alpha-glucans by cleavage of an alpha-1,4 glycosidic bond and subsequent transfer of the cleaved-off oligosaccharide to a new alpha-1,6 position (Probable). Is probably involved in the biosynthesis of 6-O-methylglucosyl lipopolysaccharides (MGLP).
Similarity
Belongs to the glycosyl hydrolase 57 family.
