Abstract
The glucan synthase 1 gene (gs-1) is required for (1,3) beta-glucan synthase activity [E.C. 2.4.1.34; UDP glucose:1,3-beta-D-glucan 3-beta-D-glucosyltransferase] and for cell wall formation. The gs-1 gene was cloned by functional complementation of the cell-wall-less defect of the (1,3) beta-glucan synthase-deficient mutant, TM1, by using a genomic Neurospora crassa cosmid library. A 2568-nucleotide gs-1 cDNA sequence revealed a 532-amino acid open reading frame encoding a polypeptide of 59 kDa. The predicted gs-1 gene product has no obvious signal peptide cleavage sites or transmembrane domains. A gs-1 null mutant is defective for cell wall formation and (1,3) beta-glucan synthase activity. The predicted GS-1 protein is weakly homologous to a putative Saccharomyces cerevisiae transcriptional regulatory protein.Entities:
