title: Isolation and characterization of the 3-phosphoglycerate kinase gene (pgk) from the filamentous fungus Trichoderma reesei.
abstract: The 3-phosphoglycerate kinase gene (pgk) from Trichoderma reesei was isolated by hybridization with the corresponding Saccharomyces cerevisiae PGK gene. The 1,545 nt long nucleotide sequence of the cloned gene codes for a 416 amino acid protein. The coding sequence contains two introns of 219 and 75 nt, respectively, at positions identical to those corresponding genes from the other filamentous fungi Aspergillus nidulans and Penicillum chrysogenum. This gene codes for two mRNAs of about 1.65 kb and 1.85 kb. The PGK protein of Trichoderma shows extensive homology to the PGKs of other fungi A. nidulans (77%), P. chrysogenum (73%) and Saccharomyces cerevisiae (69%). However, the PGKs of the two other filamentous fungi, A. nidulans and P. chrysogenum, seem to be more closely related to each other than to the T. reesei enzyme.
