ID   4.1.1.128
DE   UDP-N-acetyl-alpha-D-glucosaminuronate decarboxylase.
CA   UDP-2-acetamido-2-deoxy-alpha-D-glucuronate + H(+) = UDP-N-acetyl-alpha-
CA   D-xylosamine + CO2.
CC   -!- The enzyme has been described from pathogenic Bacillus species,
CC       including Bacillus anthracis, Bacillus thuringiensis, and Bacillus
CC       cereus.
CC   -!- The enzyme requires an NAD cofactor, and the reaction proceeds via a
CC       4-dehydro intermediate, resulting in reduction of NAD(+) to NADH (cf.
CC       EC 1.1.1.305).
CC   -!- However, NADH is not released from the enzyme and is recycled back to
CC       NAD(+) at the completion of the reaction cycle.
CC   -!- The product is incorporated into an extracellular polysaccharide
CC       known as pzX.
