The GH81 family includes proteins with endo-beta-1,3-glucanase widely distributed in yeast and fungi, which are also present in plants and bacteria. We have studied the activity of the Saccharomyces cerevisiae ScEng2 and the Schizosaccharomyces pombe SpEng1 and SpEng2 proteins. All three proteins exclusively hydrolyzed linear beta-1,3-glucan chains.(More)
Meiosis is the developmental programme by which sexually reproducing diploid organisms generate haploid gametes. In yeast, meiosis is followed by spore morphogenesis. The formation of the Schizosaccharomyces pombe ascospore wall requires the co-ordinated activity of enzymes involved in the biosynthesis and modification of its components, such as glucans.(More)
BACKGROUND The formation of the cell wall in Schizosaccharomyces pombe requires the coordinated activity of enzymes involved in the biosynthesis and modification of β-glucans. The β(1,3)-glucan synthase complex synthesizes linear β(1,3)-glucans, which remain unorganized until they are cross-linked to other β(1,3)-glucans and other cell wall components.(More)
Sporulation is a developmental variation of the yeast life cycle whereby four spores are produced within a diploid cell, with proliferation resuming after germination. The GAS family of glycosylphosphatidylinositol-anchored glucan-remodeling enzymes exemplifies functional interplay between paralogous genes during the yeast life cycle. GAS1 and GAS5 are(More)
Cell separation in Schizosaccharomyces pombe is achieved through the concerted action of the Eng1 endo-beta-1,3-glucanase and the Agn1 endo-alpha-1,3-glucanase, which are transported to the septum and localize to a ring-like structure that surrounds the septum. Correct localization of these hydrolases requires the presence of both the septins and the(More)
