Sysname
2,4,6/3,5-pentahydroxycyclohexanone 2-isomerase
Reaction(IUBMB)
2,4,6/3,5-pentahydroxycyclohexanone = 2D-2,3,5/4,6-pentahydroxycyclohexanone [RN:
R09952 ]
Reaction(KEGG)
Substrate
2,4,6/3,5-pentahydroxycyclohexanone [CPD:
C00691 ]
Product
2D-2,3,5/4,6-pentahydroxycyclohexanone [CPD:
C20251 ]
Comment
Requires a divalent metal ion for activity. Mn2+, Fe2+ and Co2+ can be used. The enzyme, found in the bacterium Bacillus subtilis, is part of the myo-inositol/D-chiro-inositol degradation pathway leading to acetyl-CoA.
