Surface properties of monomolecular films of chlorophyll (Chl), plastocyanin (Pc), cytochrome c (Cyt) and ferridoxin (Fd) were measured at a heptane-water interface. Mixed films of Chl and the other components were examined in darkness and in light. The area/molecule, A, for Fd (from Cl. pasteurianum) is much larger at a heptane-water than Fd (from spinach) at an air-water interface. This diffe...

The respiratory chain of Pseudomonas pseudoalcaligenes KF707 in membranes isolated from cells grown in the presence or absence of the toxic oxyanion tellurite (TeO3(2-)) was examined. Aerobic growth in the absence of tellurite shows an NADH-dependent respiration which is 80% catalysed by the cytochrome (cyt) bc1-containing pathway leading to two terminal membrane-bound cyt c oxidases inhibited ...

Available mitochondrial DNA sequences viz., 16S, Cyt b, Cyt c oxidase subunit - I, and Cyt c subunit-like - I gene of Rhynocoris (Kolenati) species were subjected to phylogenetic analysis to understand the intrageneric and intraspecific variations and the role of geographical isolation on speciation; using CLUSTAL W in MEGA version 5.1. This analysis includes fifteen species and four ecotypes o...

The cytoskeleton is an organelle of eukaryotic cells engaged in organization and external and internal cell movements, e.g., endocytosis. Our previous experiments proved that colchicine (an antitubular drug) and cytochalasin B (cyt B, an antimicrofilament agent) have significant influence on the development of the process [8, 9]. Reports on the inhibiting effect of the development of antibody-d...

The design of artificial metalloenzymes has achieved tremendous progress, although few designs can achieve catalytic performances comparable to that of native enzymes. Moreover, the structure and function of artificial metalloenzymes in non-native states has rarely been explored. Herein, we found that a c-type cytochrome b5 (Cyt b5), N57C/S71C Cyt b5, with heme covalently attached to the protei...

The production of superoxide anions (O2•-) by the phagocyte NADPH oxidase complex has a crucial role in destruction pathogens innate immunity. Majority vitro studies on functioning indirectly follows enzymatic reaction reduction cytochrome c (cyt c). Only few reports mention alternative approach consisting measuring consumption rate. When using membrane vesicles human neutrophils, enzyme specif...

The fabrication of bioelectrocatalytic protein electrodes by the simple compression carbon nanotube and powders was investigated using a series proteins including bilirubin oxidase (BOx), bovine serum albumin (BSA), catalase, cytochrome C (Cyt C), diaphorase, FAD-dependent glucose dehydrogenase (FAD-GDH), galactose (GAOx), (GOx), horseradish peroxidase (HRP), laccase urease. isoelectric points ...

Suitability of ATP and [Cho][Sal] to form nanostructured hydrotropes their utility in protein packaging extreme conditions are discussed. The engineered molecular nano-cages surrounding Cyt c resulted higher peroxidase activity than native with exceptionally high thermal tolerance.

Protein orientation in nanoparticle-protein conjugates plays a crucial role binding to cell receptors and ultimately, defines their targeting efficiency. Therefore, understanding fundamental aspects of the protein upon adsorption on surface nanoparticles (NPs) is vital for development clinically important protein-based nanomedicines. In this work, new insights effect different cytochrome c (cyt...
