Ribosomal phosphoproteins in Microsporum canis

Abstract

Ribosomal phosphoproteins of Microsporum canis labelled in vivo were characterised by two-dimensional and SDS polyacrylamide gel electrophoresis. A small subunit protein, S6, was the only phosphoprotein identified in 40S and 80S in basic-acidic two-dimensional gels. Three different forms of phosphorylated S6 were also observed in 40S subunit. On SDS gels five phosphoproteins were identified in 80S; of these three were present in 40S and two in 60S. S6 was the only basic phosphoprotein, while the other four were acidic.
