| Description | The cell wall β-d-glucan of Piricularia oryzae has been studied by methylation, periodate oxidation and fragmentation analysis. Hydrolysis of the methylated d-glucan afforded 2,3,4,6-tetra- (1 mole), 2,4,6-tri- (9 moles), 2,3,4-tri- (2 moles) and 2,4-di-O-methyl-d-glucose (1 mole). The degraded glucan obtained after Smith degradation was also examined by methylation analysis. Methylation of the degraded glucan, followed by subsequent hydrolysis, gave 2,3,4,6-tetra- (1 mole) and 2,4,6-tri-O-methyl-d-glucose (10 moles). Controlled acetolysis of the d-glucan afforded a homologous series of laminaridextrins, whereas enzymatic degradation with β-1,3 glucanase from Basidiomycete sp. QM 806 gave glucose, gentiobiose and gentiotriose. Additional evidence for the structure of the d-glucan has been provided by periodate oxidation studies. The glucan was oxidized by periodate, consuming 0.36 mole of periodate and producing 0.18 mole of formic acid per anhydroglucose unit. These results suggest that the cell wall β-d-glucan has a β-1,3 linked backbone with the side chains attached through β-1,6 linkages and a part of the backbone is constituted of β-1,6 linked residues. |
