CRYSTAL STRUCTURE OF SPHINGOMONAS ELODEA ATCC 31461 GLUCOSE-1-PHOSPHATE URIDYLYLTRANSFERASE IN COMPLEX WITH GLUCOSE-1-PHOSPHATE.
Overview
Gellan gum is a widely used commercial material, available in many, different forms. Its economic importance has led to studies into the, biosynthesis of exopolysaccharide gellan gum, which is industrially, prepared in high yields using Sphingomonas elodea ATCC 31461., Glucose-1-phosphate uridylyltransferase mediates the reversible conversion, of glucose-1-phosphate and UTP into UDP-glucose and pyrophosphate, which, is a key step in the biosynthetic pathway of gellan gums. Here we present, the X-ray crystal structure of the glucose-1-phosphate uridylyltransferase, from S. elodea. The S. elodea enzyme shares strong monomeric similarity, with glucose-1-phosphate thymidylyltransferase, several structures of, which are known, although the quaternary structures of the active enzymes, are rather different. A detailed comparison between S. elodea, glucose-1-phosphate uridylyltransferase and available, thymidylyltransferases is described and shows remarkable structural, similarities, despite the low sequence identities between the two, divergent groups of proteins.
