The utilization of dCTP derived from de novo synthesis through ribonucleotide reductase in exponentially growing CCRF-CEM cells was compared with the metabolic fate of dCTP produced by the salvage pathway. Exogenous dCyd was not effectively incorpora

Membrane-associated leucine aminopeptidase (EC 3.4.11.1, LAP) has been purified to homogeneity from Schistosoma mansoni egg homogenates by a combination of ultracentrifugation, chromatofocusing, and molecular sieve chromatography. A 260-fold increase

Little is known about the kinetic mechanism of E3 ubiquitin ligases. This work describes basic methodology to investigate the kinetic mechanism of E3 ubiquitin ligases. The method used steady state, bi-substrate kinetic analysis of an E3 ligase-catal

A small molecule inhibitor of NF-kappaB-dependent cytokine expression was discovered that blocked tumor necrosis factor (TNF) alpha-induced IkappaB(alpha) degradation in MM6 cells but not the degradation of beta-catenin in Jurkat cells. Ro106-9920 bl

High levels of leucine aminopeptidase (LAP) have been detected in Schistosoma mansoni eggs. In this report we demonstrate that this enzyme is immunogenic in mice infected with either S. mansoni or S. japonicum. The anti-schistosomal agent, praziquant

Schistosoma mansoni eggs were isolated and staged microscopically according to size. The eggs were then allowed to hatch and were reexamined; the hatching percentage of mature eggs was calculated. The results show clearly that not only do immature eg

Leucine aminopeptidase (LAP) activity has been measured in extracts of eggs, miracidia, cercariae and adult worms of Schistosoma mansoni. Activity measured at pH 7.2 using L-leu-7-amino-4-trifluoro-methylcoumarin as substrate is 6- to 17-fold greater
