N pi-methylhistidine in myosin-light-chain kinase

Biol Chem Hoppe Seyler. 1987 Dec;368(12):1607-11. doi: 10.1515/bchm3.1987.368.2.1607.


The identification and localization of N pi-methylhistidine (1-methylhistidine) within the primary structure (His 157) of rabbit skeletal muscle myosin-light-chain kinase is described. The data show for the first time that N pi-methylhistidine, known as a rare mammalian urine amino acid, is a protein constituent.
