Sequence-specific inhibition of a nonspecific protease.

The Role of Caspase 9 during Programmed Cell Death in Ciliary Ganglia of Chick Embryos

During programmed cell death (PCD) apoptosis is controlled by many factors such as proteases. With no specific protease (s) known during PCD in the developing nervous system so far, we sought to determine if any specific protease (s) is involved in this process and therefore used different protease inhibitors during PCD (from embryonic day 6 to 10) in chick embryos. Among the inhibitors commerc...

Determination of aspartic protease gene dosage in the Onchocerca volvulusgenome

Aspartic proteases are a relatively small group of enzymes which express in various nematodes including Onchocerca volvulus. An estimation of the gene copy number corresponding to the OV7A clone, which contains a cDNA insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of O. volvulus, was made by slot blot analysis in a closely related species O. gibsonig...

Cloning and Enhanced Expression of an Extracellular Alkaline Protease from a Soil Isolate of Bacillus clausii in Bacillus subtilis

in the detergent industry. In this study, the extracellular alkaline serine protease gene, aprE, from Bacillusclausii was amplified by PCR and further cloned and expressed in B. subtilis WB600 using the pWB980 expression vector. Protease activity of the recombinant B. subtilis WB600 harboring the plasmid pWB980/aprEreached up to 1020 U/ml, approximately 3-folds higher than the nativ...

A proteolytic fragment from the central region of p53 has marked sequence-specific DNA-binding activity when generated from wild-type but not from oncogenic mutant p53 protein.

p53 is a sequence-specific DNA-binding oligomeric protein that can activate transcription from promoters bearing p53-binding sites. Whereas the activation region of p53 has been identified within the amino terminus, the location of the specific DNA-binding domain has not been reported. Thermolysin treatment of p53 protein generates a stable protease-resistant fragment that binds with marked spe...
