Cyclophilins constitute a subgroup of large family of proteins called immunophilins, which also include FKBPs and Parvulins. They are remarkably conserved in all genera, highlighting their pivotal role in important cellular processes. Most cyclophilins display PPIase enzymatic activity, multiplicity, diverse cellular locations and active role in protein folding which render them to be included ...
Cyclophilins belong to a large family of enzymes called "peptidyl prolyl isomerases" that assist protein folding and assembly. The cyclophilin CYP20-3 (also known as "ROC4") is the only member of this group located in the stroma (soluble phase) of chloroplasts. In the present study we isolated mutant Arabidopsis plants defective in the CYP20-3 gene and found them to be hypersensitive to oxidati...
Secretion of proteins into the membrane-cell wall space is essential for cell wall biosynthesis and pathogenicity in Gram-positive bacteria. Folding and maturation of many secreted proteins depend on a single extracellular foldase, the PrsA protein. PrsA is a 30-kDa protein, lipid anchored to the outer leaflet of the cell membrane. The crystal structure of Bacillus subtilis PrsA reveals a centr...
The spontaneous reactivation yield of acidic phospholipase A2 (APLA2), a protein containing seven disulfide bonds, after reduction and denaturation in guanidine hydrochloride is very low. Protein disulfide isomerase (PDI) markedly increases the reactivation yield and prevents the aggregation of APLA2 during refolding in a redox buffer containing GSH and GSSG. S-methylated PDI (mPDI), with no is...
جهت بهینه سازی شرایط تولید پروتئین هیدرولیز شده (شامل نسبت آنزیم به سوبسترا، دما و زمان) به منظور دستیابی به بالاترین خواص آنتی اکسیدانی، مینس تهیه شده از ضایعات میگوی ببری سبز (penaeus semisulcatus) پس از تعیین درصد پروتئین آن (13%، بر اساس وزن تر) با استفاده از دو پروتئاز تجاری آلکالاز و فلاورزایم بر اساس 18 تیمار تعیین شده با طرح آزمایشات سطح پاسخ برای هر آنزیم، هیدرولیز شده و با خشک کن انجم...
