beta-Alanine catabolism in Pseudomonas fluorescens is initiated by the enzyme beta-alanine transaminase. We have isolated mutants which fail to produce this enzyme and thus cannot grow on beta-alanine as the sole nitrogen source. The accumulation of beta-alanine-1-(14)C has been studied in one of these mutants, strain 67, and in the wild type. In the mutant, beta-alanine remains in a stable int...
Purified D-amino acid transaminase from Bacillus sphaericus catalyzes an alpha,beta elimination from the D isomer of beta-chloroalanine to yield equivalent amounts of pyruvate, chloride, and ammonia; the L isomer of chloroalanine is not a substrate for this transaminase. During the beta elimination there is a synchronous loss in enzyme activity; the Kinact for beta-chloroalanine was estimated t...
Primary hyperoxaluria type I (PH1) is an autosomal-recessive inborn error of liver metabolism caused by alanine:glyoxylate aminotransferase (AGT) deficiency. In silico modeling of liver metabolism in PH1 recapitulated accumulation of known biomarkers as well as alteration of histidine and histamine levels, which we confirmed in vitro, in vivo, and in PH1 patients. AGT-deficient mice showed decr...
teucrium polium is an analgesic, antidiabetic and antilipeidemic herbal medicament. the aim of this survey was to evaluate the effect of aqueous extract t. polium on liver enzymes linked to liver dysfunction, serum lipids and glucose, in diabetic male rats. methods: a total of 20 sprague-dawly male rats became diabetic by intraperitoneal injection of streptozotocin (60 mg/kg). the animals were ...
the aim of this study was to investigate c-reactive protein (crp) level in preeclampsia (pe) and its association with the severity of the disease. this cross-sectional study included 43 women with mild pe, 43 women with severe pe, and 43 healthy pregnant. they were selected in the third trimester of pregnancy in the afzalipour hospital, kerman, iran, from march 2006 to march 2007. mean diastoli...
The characteristics of liver damage associated with the use of diclofenac, a popular nonsteroidal anti-inflammatory drug, were investigated by reviewing adverse drug reaction reports for Australia. Twenty six patients were reported for whom diclofenac was the sole suspected drug cause of their liver damage. The average age of the patients was 64 years (range 37-84 years); 19 (70%) were women. T...
Background and objectives: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by the accumulation of large amounts of fat in the hepatocytes. Given that atorvastatin is effective for treatment of NAFLD, the present study investigated effects of high-fat/fructose diet (HFFD) with atorvastatin on liver enzymes and lipid profile in a NAFLD rat model. Methods: Thirty-two m...
This study describes the functional characterization of a specific mosquito transaminase responsible for catalyzing the transamination of 3-hydroxykynurenine (3-HK) to xanthurenic acid (XA). The enzyme was purified from Aedes aegypti larvae by ammonium sulfate fractionation, heat treatment, and various chromatographic techniques, plus non-denaturing electrophoresis. The purified transaminase ha...
