Need a replacement for a manufacturer’s protocol or product datasheet? Want to re-order an enzyme, but can’t find its catalogue number? As manufacturers scramble to put their product information online, much of it can now be tracked down on the web. In this article The spider takes a subjective look at the web offerings of some of the big suppliers of products for molecular biology (if we haven...

Optimization of a serotype-selective, small-molecule inhibitor of botulinum neurotoxin serotype A (BoNTA) endopeptidase is a formidable challenge because the enzyme-substrate interface is unusually large and the endopeptidase itself is a large, zinc-binding protein with a complex fold that is difficult to simulate computationally. We conducted multiple molecular dynamics simulations of the endo...
The kallikrein kinin system (KKS) consists of serine proteases involved in the production of peptides called kinins, principally bradykinin and Lys-bradykinin (kallidin). The KKS contributes to a variety of physiological processes including inflammation, blood pressure control and coagulation. Here we review the protein structural data available for these serine proteases and examine the molecu...
The synthesis and design using molecular modeling techniques for non-peptide, low molecular weight novel fibrinogen receptor (glycoprotein IIb/IIIa: Gp IIb/IIIa) antagonists, is reported. We used a highly potent serine protease inhibitor, Nafamostat, having an amidinonaphthyl unit as the starting compound. The compounds 4-(6-amidino-2-naphthylaminocarbonyl)phenoxyacetic acid (5a) and 4-(6-amidi...

BACKGROUND Immunoglobulin (Ig) E-mediated reactions to honeybee venom can cause severe anaphylaxis, sometimes with fatal consequences. Detailed knowledge of the allergic potential of all venom components is necessary to ensure proper diagnosis and treatment of allergy and to gain a better understanding of the allergological mechanisms of insect venoms. OBJECTIVE Our objective was to undertake...
A high molecular weight protease has been purified to homogeneity from calf brain cytosol. The purification procedure involves ammonium sulfate fractionation of the cytosol followed by chromatography on DEAE-Sephacel, hydroxylapatite, concanavalin A-Sepharose 4B and Sephacryl S-300. The molecular weight of the native protease was estimated to be Mr = 465,000 by high pressure liquid chromatograp...
An alkalophilic bacterium, Bacillus cereus produced an extracellular alkaline protease, which was found to be active at high temperature and pH range, suitable for commercial laundry detergents. B. cereus protease was partitioned in different aqueous two-phase systems such as PEG/dextran, PEG/potassium phosphate, PEG/sodium citrate, PEG/magnesium sulphate and PEG/sodium dihydrogen phosphate and...
