Reaction: (1) ATP + valienone = ADP + valienone 7-phosphate
(2) ATP + validone = ADP + validone 7-phosphate
Glossary: valienone = (4R,5S,6R)-4,5,6-trihydroxy-3-(hydroxymethyl)cyclohex-2-en-1-one
validone = (2R,3S,4R,5R)-2,3,4-trihydroxy-5-(hydroxymethyl)cyclohexan-1-one
Other name(s): valC (gene name); vldC (gene name)
Systematic name: ATP:C7-cyclitol 7-phosphotransferase
Comments: The enzyme, characterized from the bacterium Streptomyces hygroscopicus var. jinggangensis, is involved in the biosynthesis of the antifungal agent validamycin A.
