title: Yeast pyruvate carboxylase: gene isolation.
abstract: To improve our understanding of pyruvate carboxylase (PC)(EC 6.4.1.1) structure and the evolution of the biotin-dependent carboxylases we have isolated and sequenced a yeast (Saccharomyces cerevisiae) genomic DNA fragment encoding PC. The identity of the cloned gene was confirmed by comparing the encoded protein with the sequence of a 26 amino acid biotin-containing peptide isolated from yeast PC. The yeast PC sequence is homologous (43% amino acid homology) to the rat PC sequence, although the carboxyl-terminus was found to be 44 residues from the biotinyl-lysine whereas in all biotin carboxylases sequenced to date the biotin is 35 residues from the carboxyl-terminus.
