SUMMARY OBJECTIVE: In this study, we aimed to determine fibroblast growth factor 23, soluble alpha klotho, osteocalcin, indoxyl sulphate, sclerostin, Procollagen 1 N Terminal Propeptide, and beta-CrossLaps levels in hemodialysis peritoneal dialysis patients, compare the of these markers among as well healthy individuals. METHODS: The study included 30 23 patients who were followed-up for at lea...
A major alginate lyase, FlAlyA, was purified from the periplasmic fraction of an alginate-assimilating bacterium, Flavobacterium sp. strain UMI-01. FlAlyA showed a single band of ~30 kDa on SDS-PAGE and exhibited the optimal temperature and pH at 55 °C and pH 7.7, respectively. Analyses for substrate preference and reaction products indicated that FlAlyA was an endolytic poly(mannuronate) lyase...
Association of cardiotrophin-1 with myocardial fibrosis in hypertensive patients with heart failure.
Cardiotrophin-1 has been shown to be profibrogenic in experimental models. The aim of this study was to analyze whether cardiotrophin-1 is associated with left ventricular end-diastolic stress and myocardial fibrosis in hypertensive patients with heart failure. Endomyocardial biopsies from patients (n=31) and necropsies from 7 control subjects were studied. Myocardial cardiotrophin-1 protein an...
The eukaryotic 20S proteasome is responsible for the degradation of many cellular proteins, but how it is assembled and how its distinct active sites are formed are not understood. Like other proteasome subunits, the yeast Doa3 protein is synthesized in precursor form. We show that the N-terminal propeptide is required for Doa3 incorporation into the proteasome and, remarkably, that the propept...
The vitamin K-dependent carboxylase catalyzes the posttranslational modification of specific glutamic acid residues to form gamma-carboxyglutamic acid residues within the vitamin K-dependent proteins. This enzyme recognizes the gamma-carboxylation recognition site on the propeptide of the precursor forms of the vitamin K-dependent blood coagulation proteins. To purify this enzyme to homogeneity...
A 355 cauliflower mosaic virus promoter and a tapetum-specific promoter were used to direct the synthesis in tobacco of preproactinidin and a derivative that lacked a C-terminal extension. Preproactinidin was processed into a form that migrated identically on protein gels with mature actinidin extracted from kiwifruit. This protein was proteolytically active in vitro, and high-level accumulatio...
مالاریا یکی از بیماری های مهم انگلی در کشورهای گرمسیری دنیا است. پلاسمودیوم فالسیپاروم انگل تک یاخته ای است که تب سه یک بدخیم را ایجاد می کند. آنتی ژن های پلاسمودیوم فالسیپاروم در سطح انگل یا در سطح سلول های آلوده ،کاندیداهای عمده جهت تولید واکسن می باشند، مانند: msp 1 و msp2 . کربوهیدرات های متصل به پروتئین های انگل مالاریا بعنوان اپی توپ های آنتی ژنیک مطرح بوده و بوسیله سیستم ایمنی میزبان تشخ...
The vacuolar hydrolase protease B in Saccharomyces cerevisiae is synthesized as an inactive precursor (Prb1p). The precursor undergoes post-translational modifications while transiting the secretory pathway. In addition to N- and O-linked glycosylations, four proteolytic cleavages occur during the maturation of Prb1p. Removal of the signal peptide by signal peptidase and the autocatalytic cleav...
