Selective inactivation of four rat liver microsomal androstenedione hydroxylases by chloramphenicol analogsStevens, Jeffrey Charles, 1963- January 1988 (has links)
The steroid androstenedione has been shown to be a valuable tool for the study of selective inactivation of rat liver cytochrome P-450 isozymes. The validity of this method was investigated using microsomes, purified cytochromes P-450, cytochrome P-450 antibodies, and the mechanism-based inactivator chloramphenicol. Enzyme inactivation and antibody inhibition studies show that microsomes from phenobarbital- and non-phenobarbital-treated rats are needed to accurately monitor the inactivation of the major phenobarbital-inducible P-450 isozyme (PB-B) and of the major constitutive androstenedione 16-alpha hydroxylase (UT-A). Enzyme inactivation studies showed that the antibiotic chloramphenicol caused different rates of NADPH-dependent enzyme inactivation among four androstenedione hydroxylases (16-beta > 6-beta > 16-alpha > 7-alpha). The results with twelve chloramphenicol analogs show that their selectivity as cytochrome P-450 inactivators is dependent upon at least three structural features: (1) the number of halogen atoms, (2) the presence of a para-nitro group on the phenyl ring, and (3) substitutions on the ethyl side chain.

Characterization of Human Glucose-6-Phosphate Isomerase of Different SizesSun, An Qiang 12 1900 (has links)
Glucose phosphate isomerase (GPI) was purified from human placenta utilizing cross-linked spherical particle phosphocellulose. In three steps, GPI could be purified approximately 5500 fold with greater than 50% recovery. The purified enzyme exhibited four bands upon non-denaturing PAGE and isoelectric focusing (IEF) when stained with GPI specific activity stain. The four isozymes were isolated by preparative IEF. The isoelectric points of the isozymes were determined. Sodium dodecyl sulfate (SDS) gel electrophoresis showed two types of subunits with different molecular weights. Structural analyses showed both types of subunits had blocked amino termini. Other properties of the isozymes and subunits, including immunological reactivity, pH stability, peptide mapping and amino acid composition, were also established.

Structure, hormonal regulation and chromosomal location of genes encoding barley (1-4)-B-xylan endohydrolasesBanik, Mitali. January 1996 (has links) (PDF)
Bibliography: leaves 127-166. This study describes the isolation, sequencing and characterization of two cDNAs encoding barley (1-4)-B-xylanase isoenzymes X-I and X-II and the gene corresponding to isoenzyme X. The results of genomic Southern blot analyses indicate that the barley (1-4)-B-xylanase gene family consists of at least 3 genes which are mapped to a single locus on the long arm of chromosome 7(5H). The cDNA is used to monitor tissue-specific expression, developmental regulation and hormonal control of the (1-4)-B-xylanase genes.
