Fluorometry of citrate in serum, with use of citrate (pro-3S)-lyase.
We describe a procedure for enzymatic assay of citrate in human serum. The citrate is degraded to acetate and oxaloacetate with citrate oxaloacetate-lyase (pro-3S-CH2-COO- yields acetate) (EC 4.1.3.6). Some oxaloacetate loses CO2 to form pyruvate. Addition of malate and lactate dehydrogenases (EC 1.1.1.37 and 1.1.1.27) permits determination of the oxaloacetate and pyruvate generated, and thus o...
متن کاملCitrate in urine determined with a new citrate lyase method.
An enzyme-spectrophotometric method to determine citrate in biological fluids is proposed, based on citrate lyase-catalyzed and phenylhydrazine reactions. The enzyme converts citrate into oxaloacetate, which, in the presence of phenylhydrazine, is transformed into the corresponding phenylhydrazone. The ultraviolet-absorbing product is determined by absorbance measurement at 330 nm. The method i...
متن کاملACLY (ATP citrate lyase)
Other names: ACL, ATPCL, CLATP HGNC (Hugo): ACLY Location: 17q21.2 Note Note that the International Union for Biochemistry and Molecular Biology (IUBMB)'s enzyme nomenclature accepts ATP citrate synthase as the name for ACLY's encoded protein (EC 2.3.3.8). However, ATP citrate lyase is more commonly used and other names include citrate cleavage enzyme, ATP-citrate (pro-S)-lyase, ATPCL, CLATP. A...
متن کاملAdenosine Triphosphate Citrate Lyase in Hypocitraturia
Chronic metabolic acidosis increases proximal tubular citrate uptake and metabolism. The present study addressed the effect of chronic metabolic acidosis on a cytosolic enzyme of citrate metabolism, ATP citrate lyase. Chronic metabolic acidosis caused hypocitraturia in rats and increased renal cortical ATP citrate lyase activity by 67% after 7 d. Renal cortical ATP citrate lyase protein abundan...
متن کاملATP-citrate lyase deficiency in the mouse.
ATP-citrate lyase (Acly) is one of two cytosolic enzymes that synthesize acetyl-coenzyme A (CoA). Because acetyl-CoA is an essential building block for cholesterol and triglycerides, Acly has been considered a therapeutic target for hyperlipidemias and obesity. To define the phenotype of Acly-deficient mice, we created Acly knockout mice in which a beta-galactosidase marker is expressed from Ac...
