Display the reaction diagram Show all sequences 2.6.1.87UDP-beta-L-threo-pentapyranos-4-ulose + L-glutamate ArnB catalyzes the reversible transfer of the amino group from glutamate to the acceptor, uridine 5'-(beta-L-threo-pentapyranosyl-4''-ulose diphosphate), the intermediate that is synthesized by ArnA from UDP-glucuronic acid.the enzyme is highly selective for glutamate as the amine donor, but the equilibrium constant in the direction of UDP-4-amino-4-deoxy-beta-L-arabinose formation is unfavorable
Display the reaction diagram Show all sequences 2.6.1.87UDP-beta-L-threo-pentapyranos-4-ulose + L-glutamate lipid A modification with 4-amino-4-deoxy-L-arabinose confers on certain pathogenic bacteria, such as Salmonella, resistance to cationic antimicrobial peptides, including those derived from the innate immune system ArnB catalysis of amino group transfer from glutamic acid to the 4''-position of a UDP-linked keto-pyranose molecule to form UDP-4-amino-4-deoxy-L-arabinose represents a key step in the lipid A modification pathway
