Disease relevance of Carboxyphosphonoenolpyruvate

• The mutase gene bears significant similarity to one other gene in the available data bases, that of carboxyphosphonoenolpyruvate mutase from Streptomyces hygroscopicus, an enzyme that catalyzes a closely related transformation [1].

High impact information on Carboxyphosphonoenolpyruvate

• Comparative analysis of structure-function relationships within the superfamily suggests that carboxyphosphonoenolpyruvate synthase, another member of the superfamily, does not catalyze the reaction proposed in the literature but catalyzes an enolase-like reaction instead [2].
• The carboxyphosphonoenolpyruvate synthase-encoding gene from the bialaphos-producing organism Streptomyces hygroscopicus [3].
• Comparison of the predicted peptide sequence of pSR132 with other proteins compiled in the NBRF data base revealed significant homology with carboxyphosphonoenolpyruvate mutase and phosphoenolpyruvate mutase from Streptomyces hygroscopicus and Tetrahymena pyriformis, respectively [4].
• Nucleotide sequence of a carboxyphosphonoenolpyruvate phosphonomutase gene isolated from a bialaphos-producing organism, Streptomyces hygroscopicus, and its expression in Streptomyces lividans [5].
• The kinetics for the mutase reaction have been evaluated for the substrate, carboxyphosphonoenolpyruvate, and for the putative reaction intermediate carboxyphosphinopyruvate, both of which have been prepared by chemical synthesis [6].

Biological context of Carboxyphosphonoenolpyruvate

• An open reading frame has been identified that encodes a protein of molecular mass 32700 Da, in good agreement with the subunit molecular mass of the carboxyphosphonoenolpyruvate mutase recently isolated from this source [Hidaka, T., Imai, S., Hara, O., Anzai, H., Murakami, T., Nagaoka, K. & Seto, H. (1990) J. Bacteriol. 172, 3066-3072] [6].
