The intact ion yields of phosphotyrosine, phosphothreonine and mono- and diphosphoserine residue-containing peptides have been compared with the non-phosphorylated sequences using plasma desorption(More)
We have isolated and sequenced a cDNA encoding the alpha subunit of phosphorylase kinase from rabbit fast-twitch skeletal muscle. The cDNA molecule consists of 388 nucleotides of 5'-nontranslated(More)
A method is described that permits the phosphoserine content of proteins and peptides to be determined in picomolar amounts. A micro-batch reaction first converts phosphoserine into S-ethylcysteine.(More)
