Wang Ch., Xu F., Li D., Zhang M. (2015): Physico-chemical and structural properties of four rice bran protein fractions based on the multiple solvent extraction method. Czech J. Food Sci., 33: 283–291. The physicochemical and structural properties of the concentrated rice bran protein (CRBP) and rice bran protein fractions – RBPF (albumin, globulin, prolamin, and glutelin) were investigated on ...

protein tyrosine phosphatases (ptpases) regulate tyrosine phosphorylation of target proteins involved in several aspects of cellular functions. enzyme activities of the ptpases in cytosolic and particulate fractions of rat ascites hepatoma cell lines were determined and compared with those of normal rat liver. our present data revealed that although there was no neoplatic-specific alteration of...

Zinc-binding proteins from seminal plasma (ZnBPs) originate in the secretions of different accessory sex glands and are implicated in key events associated with sperm-egg fertilization processes. This study describes the isolation and characterization of the ZnBPs of canine seminal plasma. Ejaculates were collected from three crossbred dogs for a 2-week period. The ZnBPs as well as non zinc-bin...

RNA synthesis in the venom glands of Crotalus durissus terrificus was stimulated by the manual extraction of the venom (milking). RNA was extracted from venom glands activated by milking and fractionated by centrifugation through sucrose density gradients. Template activity for protein synthesis and base composition of the RNA fractions were studied. RNA fractions that sediment between 18S and ...

G protein βγ subunits play essential roles in regulating cellular signaling cascades, yet little is known about their distribution in tissues or their subcellular localization. While previous studies have suggested specific isoforms may exhibit a wide range of distributions throughout the central nervous system, a thorough investigation of the expression patterns of both Gβ and Gγ isoforms with...

expression of htlv-i p19 protein in an escherichia coli expression system always leads to the formation of inclusion body. solubilisation and refolding of the inclusion bodies is complex, time consuming and difficult during large-scale preparation. this study aimed to express and purify a soluble form of recombinant htlv-i p19 protein in an e. coli expression system. the synthetic dna encoding ...

Objective(s): Artemisia species are important medicinal plants throughout the world. Some species are traditionally used for their anti-inflammatory effect. The present study was designed to isolate sesquiterpene fractions from several Artemisia species and evaluate their anti-inflammatory activities on key mediators and signaling molecules involved in regulation of in...

Spent yeast is one of the main fermentation process by-products and several bioactive ingredients have been extracted from it, such as mannans β-glucans. These extraction processes generate waste streams rich in protein, that can still be used to produce peptide-rich extracts. This work describes use a scalable low-cost obtain peptide extracts circular economy concept. Peptide fractions produce...
