Assembly of the cytolytic alternative pathway of complement from 11 isolated plasma proteins

Journal of Experimental Medicine, 1978
The known cytolytic function of the alternative pathway in serum was quantitatively reproduced by combining 11 isolated plasma proteins at their respective serum concentrations.

Detection by Paper Electrophoresis of the Protein Denaturation in Heat-inactivated Serum for the Complement Fixation Reaction [PDF]

Nature, 1956
IN seeking the mechanism to explain an apparent procomplementary activity to canine complement of canine serum activated at 56° C. for 30 min., it was observed that the same serum was anticomplementary if inactivated at 62° C. instead of 56° C.

Buoyancy regulation and aggregate formation in Amoebobacter purpureus from Mahoney lake [PDF]

, 1992
The meromictic Mahoney Lake (British Columbia, Canada) contains an extremely dense layer of purple sulfur bacteria (Amoebobacter purpureus). The buoyant density of Amoebobacter cells grown in pure culture at saturating light intensity was significantly ...

Studies of the molecular mechanisms of C3b inactivation and a simplified assay of beta 1H and the C3b inactivator (C3bINA).

Journal of Immunology, 1979
A sensitive radio assay was developed to evaluate and quantitate the function of the control proteins important in the cleavage of cell-bound C3b and in the release of the subfragment C3c.

Piceatannol, a Natural Polyphenol From Grape, Inhibits Helicobacter pylori Through Targeted Suppression of Its Secreted Urease

Food Science &Nutrition, Volume 13, Issue 9, September 2025.
Piceatannol significantly inhibits the growth of Helicobacter pylori through targeted suppression of its secreted urease activity. The inhibition of piceatannol against H. pylori urease (HPU) and jack bean urease (JBU) was characterized in a slow‐binding, mixed‐type and slow‐binding, noncompetitive type, respectively.

Detection of Sulfoquinovosidase Activity in Cell Lysates Using Activity‐Based Probes

Angewandte Chemie, Volume 136, Issue 26, June 21, 2024.
The development of activity‐based probes targeting the active site nucleophile of glycoside hydrolase family 31 sulfoquinovosidases is described. The probes are shown to bind covalently by structural biology, mass spectrometry and Cy5 in‐gel fluorescence, are selective for sulfoquinovosidases in whole bacterial cell lysates, and are used to monitor ...

Beyond the Binary: Controlling Natural Sex‐Change in Hermaphroditic Fishes

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Sex‐change in hermaphroditic fishes is a complex but natural biological phenomenon that has significant implications for aquaculture fingerling production, selective breeding, and grow‐out. Understanding the physiological, endocrinological, and molecular pathways underlying hermaphroditism in fishes offers unique opportunities to manipulate ...

Relevance of G protein‐coupled receptor (GPCR) dynamics for receptor activation, signalling bias and allosteric modulation

British Journal of Pharmacology, Volume 182, Issue 14, Page 3211-3224, July 2025.
Abstract G protein‐coupled receptors (GPCRs) are one of the major drug targets. In recent years, computational drug design for GPCRs has mainly focused on static structures obtained through X‐ray crystallography, cryogenic electron microscopy (cryo‐EM) or in silico modelling as a starting point for virtual screening campaigns. However, GPCRs are highly

Interaction of S-protein of complement with thrombin and antithrombin III during coagulation. Protection of thrombin by S-protein from antithrombin III inactivation.

Journal of Biological Chemistry, 1986
S-protein, the inhibitor in plasma of the membrane attack complex of complement, appears to have a second function in coagulation. S-protein during clotting enters into a trimolecular complex with thrombin and antithrombin III (ATIII). Functionally, S-protein in the presence of low concentrations of heparin, protects thrombin from inactivation by ATIII.
