Glutathione (GSH), trypanothione (T(SH)2) and glutathionyl spermidine (GSH-SP) concentrations were determined in the Tulahuén and LQ strains and the DM 28c clone of Trypanosoma cruzi. The concentrations of GSH, T(SH)2 and GSH-SP, expressed as nmol o

1. 1. Six cytochrome P-450 species have been purified to varying extents from microsomes obtained from ecdysone-induced house fly larvae by the use of octylamino Sepharose-4B, Synchropak AX-300, Synchropak CM-300 and TSK-DEAE-5 PW column chromatograp

Six forms of cytochrome P-450 in the mitochondria of larvae from Musca domestica were isolated by solubilization with CHAPS followed by ammonium sulfate fractionation and HPLC on an anion-exchange column. Forms 1, 2, 3, 5, and 6 catalyzed the formati

Two approaches may be used to study the function of cytochrome P-450 in insects: (a) an evaluation of the spectral and catalytic properties of the hemoprotein while associated with microsomal membranes; (b) the solubilization, resolution and purifica

1. 1. Evidence is presented suggesting that a single enzyme catalyzes the conjugation of methyl iodide and 1-chloro-2,4-dinitrobenzene (spec. act., 2.25 nmol/mg protein per min and 86.8 nmol/mg protein per min, respectively). 2. 2. The enzyme has a m

1. 1. mRNA isolated from larval Taenia crassiceps directs efficiently the synthesis of proteins in cell-free heterologous systems. 2. 2. Part of the newly synthesized proteins in a reticulocyte system are precipitable by a rabbit antiserum against T.

1. 1. Microsomal fractions from Trypanosoma cruzi epimastigotes catalyze the hydration of styrene oxide to styrene glycol. The activity is linear up to 45 min of incubation is proportional to microsomal protein concentration within certain range, and

Larval Taenia crassiceps has an active, cell-free protein synthesis system. The system, which consists of polysomes and a pH 5 fraction, is dependent on ATP, GTP, Mg 2+ , K + , and an ATP-generating system and is sensitive to RNase and puromycin unde
