ISOZYMES OF THE PENTOSE PHOSPHATE PATHWAY

摘要: ABSTRACT. There are two primary forms of the enzymes pentose phosphate pathway in Candida utilis, a yeast that can grow on pentoses as well hexoses. Trans-aldolase, one this pathway, has an additional form which is hybrid formed by exchange subunits other isozymes. no differences kinetic properties these isozymes; their only difference lies structure, indicating different genetic origin shown sequence peptide from active site transaldolase I and III. In peptide, substitution tyrosine residue histidine observed. Even though there identical chains isozymes or III, single be detected. The participation lysine role neighboring cysteine mechanism action enzyme discussed.
