A spectrofluorimetric assay of calmodulin-dependent protein phosphatase using 4-methylumbelliferyl phosphate. 1986

F A Anthony, and D L Merat, and W Y Cheung

A continuous spectrofluorimetric assay of calmodulin-dependent phosphatase is described. The assay monitors the formation of a fluorescent 4-methylumbelliferone from the dephosphorylation of 4-methylumbelliferyl phosphate and detects as little as 1 pmol of 4-methylumbelliferone. The phosphatase shows a Km of 1.3 mM for the substrate and a Vmax of 100 nmol/mg/min.

UI	MeSH Term	Description	Entries
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D002148	Calmodulin-Binding Proteins	Proteins which bind calmodulin. They are found in many tissues and have a variety of functions including F-actin cross-linking properties, inhibition of cyclic nucleotide phosphodiesterase and calcium and magnesium ATPases.
