Abstract

SUMMARY

Aminoacetone was formed from - or - -aminopropan-2-ol, or both, by a variety of micro-organisms. An oxidoreductase capable of oxidizing --aminopropan-2-ol to aminoacetone was purified 38-fold from It was inactive with - -aminopropan-2-ol, -threonine and -glycerol-1-phosphate. It was highly active with a variety of diols and hydroxyketones and not narrowly specific as reported by other workers (Dekker & Swain, 1968). The effect of growth conditions on activity suggested involvement in mono- or di-hydroxyacetone metabolism. Although --aminopropan-2-ol oxidation was demonstrated in crude extracts of a number of other bacteria, a relationship between -threonine and --aminopropan-2-ol dehydrogenases and vitamin B biosynthesis does not appear likely.
