ID 4.1.1.82 DE phosphonopyruvate decarboxylase. AN 3-phosphonopyruvate carboxy-lyase. CA 3-phosphonopyruvate + H(+) = CO2 + phosphonoacetaldehyde. CC -!- Catalyzes a step in the biosynthetic pathway of CC 2-aminoethylphosphonate, a component of the capsular polysaccharide CC complex of Bacteroides fragilis. CC -!- Activated by the divalent cations Mg(2+), Ca(2+) and Mn(2+). CC -!- Pyruvate and sulfopyruvate can also act as substrates, but more CC slowly. DR Q54271, PPD_STRHY ; O86938, PPD_STRVT ; //
