Accepted name: acarbose 7IV-phosphotransferase

Reaction: ATP + acarbose = ADP + acarbose 7IV-phosphate

Glossary: acarbose = 4,6-dideoxy-4-{[(1S,4R,5S,6S)-4,5,6-trihydroxy-3-(hydroxymethyl)-2-cyclohexen-1-yl]amino}-α-D-glucopyranosyl-(1→4)-α-D-glucopyranosyl-(1→4)-β-D-glucopyranose

Other name(s): acarbose 7-kinase; AcbK

Systematic name: ATP:acarbose 7IV-phosphotransferase

Comments: The enzyme, characterized from the bacterium Actinoplanes sp. SE50/110, is specific for acarbose.
