Modulation by phosphorylation of glycogen phosphorylase-sarcoplasmic reticulum interaction.

abstract：:The structure of rabbit liver Hsp90 was reevaluated by limited trypsinolysis, N-terminal sequencing and determination of the site that is phosphorylated by casein kinase II. Limited proteolysis results in formation of four groups of large peptides with M(r) in the range of 26-41 kDa. Peptides with M(r) 39-41 kDa were ...
