We examined the ability of acid phosphatases formed by various subunit combinations to be excreted into the medium. Plasmids with repressible acid phosphatase structural genes under control of the yeast glyceraldehyde-phosphate dehydrogenase (GAP) promoter were constructed to obtain constitutive expression of acid phosphatase, and yeast strains with disruptions in PHO5, PHO10 and PHO11, respectively, were used to generate mutants expressing single genes or specific gene combinations. EndoF treatment of acid phosphatases, produced by these strains, followed by SDS-electrophoresis in combination with densitometry techniques revealed that the ratio p60/(p56 + p58) among structural polypeptides in extracellular enzyme is constant and equals to 6.0. A study of acid phosphatases formed by single type subunits was undertaken. Expression products of PHO5, PHO10 and PHO11 genes were isolated from the culture medium. The specific activities of the enzymes were found to be 33, 2 and 2 mM x mg-1 x min-1, respectively. The values of Mr estimated by HPLC chromatography for the enzymes encoded for by the genes PHO5, PHO10 and PHO11 and SDS-polyacrilamide gel electrophoresis data suggested an oligomeric organisation of the enzymes. Isoelectric focusing in polyacrylamide gel with immobilised pH gradient followed by activity staining yielded numerous sharp bands of homopolymeric acid phosphatases forms being different in their pI. The kinetic characterisation of the enzymes revealed differences in Km values, sensitivity to temperature inactivation, inhibition by orthophosphate and the effect of pH on the enzyme activity."xsd:string |
