ID 1.1.1.335 DE UDP-N-acetyl-2-amino-2-deoxyglucuronate dehydrogenase. CA NAD(+) + UDP-N-2-acetamido-2-deoxy-alpha-D-glucuronate = H(+) + NADH + CA UDP-2-acetamido-2-deoxy-alpha-D-ribo-hex-3-uluronate. CC -!- This enzyme participates in the biosynthetic pathway for UDP-alpha-D- CC ManNAc3NAcA (UDP-2,3-diacetamido-2,3-dideoxy-alpha-D-mannuronic CC acid), an important precursor of B-band lipopolysaccharide. CC -!- The enzymes from Pseudomonas aeruginosa serotype O5 and Thermus CC thermophilus form a complex with the the enzyme catalyzing the next CC step the pathway (EC 2.6.1.98). CC -!- The enzyme also possesses an EC 1.1.99.2 activity, and utilizes the CC 2-oxoglutarate produced by EC 2.6.1.98 to regenerate the tightly CC bound NAD(+). CC -!- The enzymes from Bordetella pertussis and Chromobacterium violaceum CC do not bind NAD(+) as tightly and do not require 2-oxoglutarate to CC function. DR G3XD23, WBPB_PSEAE ; //
