abstract plant nonspecific lipid transfer proteins (nsltps) are divided into nsltp1 and nsltp2. the existence of an internal hydrophobic cavity, is a typical characteristic of nsltps that serves as the binding site for lipid substrates. in this communication a simple, rapid and low-cost alternative method was developed for purification of nsltp2 from rice paddy. after extracting, final supernat...

background: candida species are among the most common causes of opportunistic fungal diseases. among candida species, candida albicans is responsible for most infections. having many strains, c. albicans is very polymorph. c. dubliniensis is very similar to albicans species both morphologically and physiologically. for an infection to occur, cell wall proteins play an important role as they ena...

hepatitis c virus (hcv) is an important agent causing chronic liver infection, which often leads to liver cirrhosis and lethal hepatocellular carcinoma (hcc). at present, there is no effective hcv vaccine for prevention of hepatic disease and the standard treatment is neither economical nor fully effective in all the patients. however, vaccination based on structural and nonstructural proteins ...

introduction: misunderstanding enzyme structure and function is a major problem of biochemical education. the purpose of this work was to consider the general features of structure and function of proteins and enzymes relevant to an understanding of structure and function of proteins and enzymes by modeling experiments. methods: a total of 109 medical students of babol university of medical sci...

the edible mushrooms (basidomycetes) have high nutritional value, promote the immune system, and as a source of natural antimicrobial substances have been used to cure bacterial infections since ancient times.various kinds of proteins with several biological activities are produced by mushrooms. in this research, in order to evaluate antibacterial activity of edible mushrooms, we isolated prote...

The interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. Rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. At different time intervals, plasma and urine samples were collected. The binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-i...

Background: Hepatitis C virus (HCV) is a main public health problem causing chronic liver infection and subsequently liver cirrhosis and lethal hepatocellular carcinoma (HCC). Vaccination based on HCV capsid proteins has attracted a special interest for prevention of viral infections. The core protein is a basic and evolutionary most conserved protein, which regulates the cellular processes rel...

Peptide and protein drugs have found an important position in therapeutics. Recent advances in pharmaceutical biotechnology have led to an increase in the number of protein products in the market. As these therapeutic proteins and peptides are made available, it will be essential to formulate these drugs into safe and effective delivery systems. The twenty different naturally occurring amin...

soils bacteria are frequently faced with various adverse environmental conditions and have developed a complex regulatory network to respond rapidly to environmental changes. in this study usefulness and applicability of stress proteins of bacteria which are produced after stress conditions were examined. the adaptation of soil bacteria involves the induction of stress proteins provide a nonspe...

background : rhoptries are unique secretory/excretory organelles that are found exclusively in the apicomplexa, and their contents are discharged at the time of invasion and are critical in the establishment of productive infection. several rhoptry proteins have been identified in toxoplasma gondii , plasmodium falciparum and neospora caninum and have been linked not only with the parasites’ ad...
