Hexose phosphate synthetase from Methylococcus capsulatus makes d-arabino-3-hexulose phosphate

Abstract

The product of the reaction catalysed by hexose phosphate synthase prepared from Methylococcus capsulatus was dephosphorylated and the sugar moiety purified. The sugar and derivatives were compared by various chromatographic and other methods with authentic samples of allulose (psicose), d-erythro-l-glycero-3-hexulose and d-erythro-d-glycero-3-hexulose. The sugar is not allulose, as was previously thought on the basis of less extensive evidence (Kemp & Quayle, 1966), but is in fact d-erythro-l-glycero-3-hexulose (d-arabino-3-hexulose). This identification is consistent with recent studies which have shown that hexose phosphate synthase catalyses the condensation of formaldehyde with d-ribulose 5-phosphate rather than with d-ribose 5-phosphate (Kemp, 1972).
