Recombinant expression, purification, and biochemical characterization of chondroitinase ABC II from Proteus vulgaris.
Chondroitin lyases (or chondroitinases) are a family of enzymes that depolymerize chondroitin sulfate (CS) and dermatan sulfate (DS) galactosaminoglycans, which have gained prominence as important players in central nervous system biology. Two distinct chondroitinase ABC enzymes, cABCI and cABCII, were identified in Proteus vulgaris. Recently, cABCI was cloned, recombinantly expressed, and exte...
متن کاملChondroitinase ABC I from Proteus vulgaris: cloning, recombinant expression and active site identification.
GalAGs (galactosaminoglycans) are one subset of the GAG (glycosaminoglycan) family of chemically heterogeneous polysaccharides that are involved in a wide range of biological processes. These complex biomacromolecules are believed to be responsible for the inhibition of nerve regeneration following injury to the central nervous system. The enzymic degradation of GAG chains in damaged nervous ti...
متن کاملBiochemical characterization of the chondroitinase ABC I active site.
cABC I (chondroitinase ABC I) from Proteus vulgaris is a GalAG (galactosaminoglycan) depolymerizing lyase that cleaves its substrates at the glycosidic bond via beta-elimination. cABC I cleaves a particularly broad range of GalAG substrates, including CS (chondroitin sulphate), DS (dermatan sulphate) and hyaluronic acid. We recently cloned and recombinantly expressed cABC I in Escherichia coli,...
متن کاملExpression, purification and kinetic characterization of recombinant benzoate dioxygenase from Rhodococcus ruber UKMP-5M
In this study, benzoate dioxygenase from Rhodococcus ruber UKMP-5M was catalyzed by oxidating the benzene ring to catechol and other derivatives. The benzoate dioxygenase (benA gene) from Rhodococcus ruber UKMP-5M was then expressed, purified, characterized, The benA gene was amplified (642 bp), and the product was cloned into a pGEM-T vector.The recombinant plasmid pGEMT-benA was digested by d...
متن کاملA Biochemical Study of Proteus Vulgaris
In this study we deal with the cultural properties, the products of growth, the pathogenicity, and the toxicity, of two strains of Proteus vulgaris, Hauser. This is an exceedingly interesting organism on account of its wide distribution, the ease with which it is modified, and because it seems to stand between the true saprophytic and the purely pathogenic bacteria. It has been found under a gr...
