Search for cellular phosphorylation products of D-allose.

The all-cis hexose D-allose, fed to hamster fibroblast cultures over 14-20 hr, brings about a striking down-regulation of hexose transport. This down-regulation by allose is inhibited by 2,4-dinitrophenol. By using D-[14C]allose and thin-layer chromatography, two types of products accumulated that have been identified as allose and allose phosphate. We suspect that allose phosphate might be the down-regulator.
