Common Namebeta-L-arabinose 1-phosphate
Descriptionbeta-L-Arabinose 1-phosphate is an intermediate in UDP-L-arabinose biosynthesis II (from L-arabinose) pathway. Although little is known about the incorporation of arabinose into these polymers or the contribution of the arabinosyl-substituents to the functions of the polymers, it has been demonstrated that arabinose-containing polymers are derived from UDP-L-arabinose, the activated sugar used by arabinosyltransferases. The formation of UDP-L-arabinose occurs via two routes: 1) a salvage pathway leading to the formation of UDP-L-arabinose from free arabinose, and 2) a de novo synthesis route involving the epimerization of UDP-D-xylose by a UDP-D-xylose 4-epimerase. The formation of UDP-L-arabinose at the end of the salvage pathway is achieved by a UDP-L-arabinose pyrophosphorylase. An enzyme with such activity has been purified from pea sprouts. This enzyme (USP for UDP-sugar pyrophosphorylase) was shown to have a broad range of monosaccharide substrates.
