Characterization and isolation of L-to-D-amino-acid-residue isomerase from platypus venom
Amino Acids, 2006Platypus venom contains an isomerase that reversibly interconverts the second amino-acid residue in some peptides between the L-form and the D-form. The enzyme acts on the natriuretic peptides OvCNPa and OvCNPb, and on the defensin-like peptides DLP-2 and DLP-4, but it does not act on DLP-1. While the isomerization of DLP-2 to DLP-4 is inhibited by the

Abstract The amplified expression of a recombinant protein is known to lead to an intracellular depletion of specific amino acid pools which in turn may affect the production of the desired protein. In order to counteract and overcome such a situation during the fermentation of the recombinant Escherichia coli (PMSG27) containing the glucose ...

3 beta-Hydroxysteroid dehydrogenase/steroid isomerase has been purified to homogeneity from bovine adrenal glands. A single protein of molecular weight 42,090 +/- 40 containing both enzyme activities has been isolated. Approximately 86% of the amino acid sequence of the bovine adrenal 3 beta-hydroxysteroid dehydrogenase/steroid isomerase has been ...

A pair of primers was synthesized according to the DNA sequence of Schistosoma japonicum Philippine strain, and the mRNA of adult worms of S. japonicum Chinese strain was prepared. The gene of triose-phosphate isomerase of S. japonicum Chinese strain (SjC TPI) was successfully cloned from the mRNA through reverse transcription polymerase chain reaction

The nucleotide sequence of a cDNA clone from Arabidopsis thaliana ecotype Columbia was determined, and the corresponding amino acid sequence deduced. The predicted sequence is highly homologous to those of members of the cyclophilin A-family of peptidyl-prolyl cis-trans isomerases.

3beta-hydroxysteroid dehydrogenase/steroid delta5-->4-isomerase (3beta-HSD/isomerase) was expressed by baculovirus in Spodoptera fungiperda (Sf9) insect cells from cDNA sequences encoding human wild-type I (placental) and the human type I mutants - H261R, Y253F and Y253,254F. Western blots of SDS-polyacrylamide gels showed that the baculovirus-infected

Although electrophoretic variation in phosphoglucose isomerase (PGI) is often detected in allozyme studies, the Pgi gene has rarely been characterized. Here, I present the cDNA sequence of the Pgi gene from two species of field cricket, Gryllus pennsylvanicus (U65475) and G.

Muconolactone isomerase is shown to be resistant to proteolytic cleavage by trypsin. Cyanogen bromide cleavage at the methionine residues of the polypeptide is at least 95% complete. Six cyanogen bromide fragments are separated on DEAE-cellulose. One fragment is shown by amino acid analysis and carboxyl-terminal analysis to be an incomplete cleavage ...

AbstractThe molecular basis of triosephosphate isomerase (TPI) deficiency was studied in 3 patients from three separate families. In all 3 patients, genomic DNA directly sequenced after amplification by the polymerase chain reaction exhibited the point mutation TPI315C amino acid 104 Glu→Asp.

The effect of vitamins (B1, B2, B3, B6, B12, H, PP and folic acid) and amino acids (glutamic and aspartic acids) on glucose isomerase biosynthesis was studied in Streptomyces albogriseolus. These compounds were added either alone or in combinations to different growth media (synthetic and complex). The results were processed using mathematical methods,
