Protein phosphatase 2a (PP2A) binds within the oligomerization domain of striatin and regulates the phosphorylation and activation of the mammalian Ste20-Like kinase Mst3
BMC Biochemistry - - 2011
Johnthan Gordon, Juyeon Hwang, Karma J Carrier, Candace A Jones, Quiana L Kern, Carlos S Moreno, Richard H Karas, David C Pallas
Striatin, a putative protein phosphatase 2A (PP2A) B-type regulatory subunit, is a multi-domain scaffolding protein that has recently been linked to several diseases including cerebral cavernous malformation (CCM), which causes symptoms ranging from headaches to stroke. Striatin association with the PP2A A/C (structural subunit/catalytic subunit) heterodimer alters PP2A substrate specificity, but ... hiện toàn bộ
Mapping of possible prion protein self-interaction domains using peptide arrays
BMC Biochemistry - Tập 8 - Trang 1-14 - 2007
Alan Rigter, Jan PM Langeveld, Drophatie Timmers-Parohi, Jorg G Jacobs, Peter LJM Moonen, Alex Bossers
The common event in transmissible spongiform encephalopathies (TSEs) or prion diseases is the conversion of host-encoded protease sensitive cellular prion protein (PrPC) into strain dependent isoforms of scrapie associated protease resistant isoform (PrPSc) of prion protein (PrP). These processes are determined by similarities as well as strain dependent variations in the PrP structure. Selective ... hiện toàn bộ
Biosynthesis and release of pheromonal bile salts in mature male sea lamprey
BMC Biochemistry - - 2013
Cory O. Brant, Yu Wen Chung-Davidson, Ké Li, Anne M. Scott, Weiming Li
Abstract Background In vertebrates, bile salts are primarily synthesized in the liver and secreted into the intestine where they aid in absorption of dietary fats. Small amounts of bile salts that are not reabsorbed into enterohepatic circulation are excreted with waste. In sexually mature male sea lamprey (Petromyzon marinus L.) a bile salt is released in large amounts across gill epithelia into ... hiện toàn bộ
Low-magnesium, trans-cleavage activity by type III, tertiary stabilized hammerhead ribozymes with stem 1 discontinuities
BMC Biochemistry - Tập 6 - Trang 1-9 - 2005
Donald H Burke, S Travis Greathouse
Low concentrations of free magnesium in the intracellular environment can present critical limitations for hammerhead ribozymes, especially for those that are designed for intermolecular (trans) cleavage of a host or pathogen RNA. Tertiary stabilizing motifs (TSM's) from natural and artificial ribozymes with a "type I" topology have been exploited to stabilize trans-cleaving hammerheads. Ribozymes... hiện toàn bộ
Mechanism of acetaldehyde-induced deactivation of microbial lipases
BMC Biochemistry - Tập 12 Số 1 - Trang 1-13 - 2011
Franken, Benjamin, Eggert, Thorsten, Jaeger, Karl E, Pohl, Martina
Microbial lipases represent the most important class of biocatalysts used for a wealth of applications in organic synthesis. An often applied reaction is the lipase-catalyzed transesterification of vinyl esters and alcohols resulting in the formation of acetaldehyde which is known to deactivate microbial lipases, presumably by structural changes caused by initial Schiff-base formation at solvent a... hiện toàn bộ
Preferential inhibition of xanthine oxidase by 2-amino-6-hydroxy-8-mercaptopurine and 2-amino-6-purine thiol
BMC Biochemistry - Tập 8 - Trang 1-11 - 2007
Sukirti Kalra, Gopabandhu Jena, Kulbhushan Tikoo, Anup Kumar Mukhopadhyay
The anticancer drug, 6-mercaptopurine (6MP) is subjected to metabolic clearance through xanthine oxidase (XOD) mediated hydroxylation, producing 6-thiouric acid (6TUA), which is excreted in urine. This reduces the effective amount of drug available for therapeutic efficacy. Co-administration of allopurinol, a suicide inhibitor of XOD, which blocks the hydroxylation of 6MP inadvertently enhances th... hiện toàn bộ
Interactions of unconjugated bilirubin with vesicles, cyclodextrins and micelles: New modeling and the role of high pKa values
BMC Biochemistry - Tập 11 - Trang 1-12 - 2010
Pasupati Mukerjee, J Donald Ostrow
Unconjugated bilirubin (UCB) is an unstable substance with very low aqueous solubility. Its aqueous pKa values affect many of its interactions, particularly their pH-dependence. A companion paper shows that only our prior solvent partition studies, leading to pKa values of 8.12 and 8.44, met all essential requirements for valid pKa determinations. Other published values, generally lower, some belo... hiện toàn bộ
A study on the two binding sites of hexokinase on brain mitochondria
BMC Biochemistry - Tập 8 - Trang 1-6 - 2007
Abolfazl Golestani, Hassan Ramshini, Mohsen Nemat-Gorgani
Type I hexokinase (HK-I) constitutes the predominant form of the enzyme in the brain, a major portion of which is associated with the outer mitochondrial membrane involving two sets of binding sites. In addition to the glucose-6-phosphate (G6P)-sensitive site (Type A), the enzyme is bound on a second set of sites (Type B) which are, while insensitive to G6P, totally releasable by use of high conce... hiện toàn bộ
Sex-different hepatic glycogen content and glucose output in rats
BMC Biochemistry - Tập 11 - Trang 1-17 - 2010
Carolina Gustavsson, Kamal Yassin, Erik Wahlström, Louisa Cheung, Johan Lindberg, Kerstin Brismar, Claes-Göran Östenson, Gunnar Norstedt, Petra Tollet-Egnell
Genes involved in hepatic metabolism have a sex-different expression in rodents. To test whether male and female rat livers differ regarding lipid and carbohydrate metabolism, whole-genome transcript profiles were generated and these were complemented by measurements of hepatic lipid and glycogen content, fatty acid (FA) oxidation rates and hepatic glucose output (HGO). The latter was determined i... hiện toàn bộ
Analysis of Escherichia coli nicotinate mononucleotide adenylyltransferase mutants in vivo and in vitro
BMC Biochemistry - Tập 6 - Trang 1-9 - 2005
Martin Stancek, Robert Schnell, Monica Rydén-Aulin
Adenylation of nicotinate mononucleotide to nicotinate adenine dinucleotide is the penultimate step in NAD+ synthesis. In Escherichia coli, the enzyme nicotinate mononucleotide adenylyltransferase is encoded by the nadD gene. We have earlier made an initial characterization in vivo of two mutant enzymes, NadD72 and NadD74. Strains with either mutation have decreased intracellular levels of NAD+, e... hiện toàn bộ
