vigna angularis/protease

Double-headed protease inhibitors I, IIa, and IIc (AB I, AB IIa, and AB IIc) have been purified from azuki beans "Takara" (Vigna angularis) by conventional chromatographic methods and their amino acid sequences have been determined. AB I, AB IIa, and AB IIc had molecular weights of 9,166, 8,661, and

The objective of this study was to evaluate the enzymatic activity of homogenates of insects fed on grain of cowpea, Vigna unguiculata (L.), cultivars grown with different nitrogen sources. For the experiment we used aliquots of the homogenate of 100 unsexed adult insects, emerged from 10 g of grain

In order to achieve high yield of fungal protease in a very cost effective way and to meet its increased market demand, current study deals with the screening of various agro-wastes as carbon source for the production of protease from Rhizopus oryzae (SN5)/NCIM-1447 under solid state fermentation.

Protease inhibitors, which are common constituents of seeds (rice, beans, and maize) have been shown to inhibit breast, colon, and skin cancers in animal experiments. Epidemiological studies have shown that diets rich in these components (ie seed proteins) decrease the occurrence of prostatic,

Trypsin inhibitor (TI) in rice bean (Vigna umbellata) varied spatio-temporally in different parts of the plant, with the highest level (30.9 mg/g d.w.) noted in the maturing seeds of genotype BRS-2 at 160 days after planting (DAP). The TI from rice bean seeds was isolated and purified approximately

Preliminary crystallographic studies of a Bowman-Birk type protease inhibitor, AB-I, from adzuki beans (Phaseolus angularis) 'Takara,' and its complex with trypsin were carried out. AB-I, MW 9100 with 82 amino acid residues, crystallizes in a trigonal space group, P3121 (or P3221), with the

The crystal structure of the complex formed by bovine trypsin and Bowman-Birk type protease inhibitor AB-I extracted from azuki beans (Vigna angularis) 'Takara' has been analyzed. The structure was solved by the application of the phase combination of single isomorphous phases and trypsin model

The hydrolysis of bradykinin (Bk) by different classes of proteases in plasma and tissues leads to a decrease in its half-life. Here, Bk actions on smooth muscle and in vivo cardiovascular assays in association with a protease inhibitor, Black eyed-pea trypsin and chymotrypsin inhibitor (BTCI) and

SH-EP is a vacuolar cysteine proteinase from germinated seeds of Vigna mungo. The enzyme has a C-terminal propeptide of 1 kDa that contains an endoplasmic reticulum (ER) retention signal, KDEL. The KDEL-tail has been suggested to function to store SH-EP as a transient zymogen in the lumen of the ER,

Extreme resistance of Arlington line cowpea (Vigna unguiculata) to Cowpea mosaic virus (CPMV) is under control of a dominant locus designated Cpa. We transiently expressed, using Tomato bushy stunt virus (TBSV) vectors and Agrobacterium tumefaciens, in nearly isogenic Cpa/Cpa and cpa/cpa cowpea

Serine protease inhibitors (PIs) have been described in many plant species and are universal throughout the plant kingdom, where trypsin inhibitors is the most common type. In the present study, trypsin and chymotrypsin inhibitory activity was detected in the seed flour extracts of 13 selected

Protease C1, an enzyme from soybean (Glycine max [L.] Merrill cv Amsoy 71) seedling cotyledons, was previously determined to be the enzyme responsible for the initial degradation of the alpha' and alpha subunits, but not the beta subunit, of beta-conglycinin storage protein. The sizes of the

The crystal structure of Bowman-Birk type protease inhibitor A-II from peanut was refined at 2.3 A resolution using a restrained least-squares method. The crystallographic R-factor is 0.196 for 7697 reflections with F > 3 sigma (F) in the range from 6.0 to 2.3 A resolution. Two molecules in an

SH-EP is a cysteine protease from germinating mung bean (Vigna mungo) that possesses a carboxyl-terminal endoplasmic reticulum (ER) retention sequence, KDEL. In order to examine the function of the ER retention sequence, we expressed a full-length cDNA of SH-EP and a minus-KDEL control in insect

Two cysteine proteinase inhibitors from cowpea, VuCys1 and VuCys2, were produced in E. coli ArcticExpress (DE3). The recombinant products strongly inhibited papain and chymopapain as well as the midgut proteases from Callosobruchus maculatus larvae, a bruchid that uses cysteine proteases as major
