BD7: Identification potential biological activity. Biodiversitas 22: 3136-3145. This study investigated the angiotensin-converting enzyme (ACE) inhibitory activity in BD7, characterizing peptide and its as a bioactive peptide. The starter cultur...

Scorpion venom contains a variety of biologically active peptides. Among them, neurotoxins are major components in the venom, but it also peptides that show antimicrobial activity. Previously, we identified three insecticidal from Liocheles australasiae scorpion, activities and structures other remained unknown. In this study, performed transcriptome analysis gland scorpion L. to gain comprehen...

Pheochromocytomas are catecholamine-producing tumors which are generally benign, but which can also present as or develop into malignancy. Molecular pathways of malignant transformation remain poorly understood. Pheochromocytomas express various trophic peptides which may influence tumoral cell behavior. Here, we investigated the expression of trophic amidated peptides, including pituitary aden...

The porcine cathelicidin PR-39 is a host defence peptide that plays a pivotal role in the innate immune defence of the pig against infections. Besides direct antimicrobial activity, it is involved in immunomodulation, wound healing and several other biological processes. In this study, the antimicrobial- and immunomodulatory activity of PR-39, and N- and C-terminal derivatives of PR-39 were tes...

Hevein and hevein-like peptides are disulfide-constrained chitin-binding cysteine-rich peptides. They are divided into three subfamilies, 6C-, 8C-, and 10C-hevein-like peptides, based on the number of cysteine residues. In addition, hevein-like peptides can exist in two forms, short and long. The long C-terminal form found in hevein and 10C-hevein-like peptides contain a C-terminal protein carg...

HLA class I presentation of pathogen-derived peptide ligands is essential for CD8+ T-cell recognition of Toxoplasma gondii infected cells. Currently, little data exist pertaining to peptides that are presented after T. gondii infection. Herein we purify HLA-A*02:01 complexes from T. gondii infected cells and characterize the peptide ligands using LCMS. We identify 195 T. gondii encoded ligands ...

C-C chemokine receptor 5 (CCR5) is a major co-receptor molecule used by HIV-1 to enter cells. This led the hypothesis that stimulating an antibody response would block HIV with minimal toxicity. Here, X-ray crystallographic studies of anti-CCR5 RoAb13 together two peptides were undertaken: one peptide 31-residue containing PIYDIN sequence and other PIDYIN alone, where part N-terminal region CCR...

In the 25 years since de Bold et al demonstrated the existence of an atrial natriuretic factor, investigation of the cardiac natriuretic peptides has produced a maturing knowledge base1,2 identifying the cardiac peptides and addressing stimuli for secretion of atrial (ANP) and B-type (BNP) natriuretic peptides, the processing and release of the mature bioactive carboxy terminal peptides, togeth...

Abstract In human cells, one third of all polypeptides enter the secretory pathway at ER. This process involves N-terminal signal peptides or internal transmembrane helices in precursors and hundred cytosolic ER proteins, which facilitate their import processing. past fifty years four pathways for targeting to Sec61 channel plus various allosteric effectors supporting stand alone membrane prote...
