Two distinct cystatin species in rice seeds with different specificities against cysteine proteinases. Molecular cloning, expression, and biochemical studies on oryzacystatin-II.

Molecular cloning of a cysteine proteinase inhibitor of rice (oryzacystatin). Homology with animal cystatins and transient expression in the ripening process of rice seeds.

A cDNA clone for a cysteine proteinase inhibitor of rice (oryzacystatin) was isolated from a lambda gt10 cDNA library of rice immature seeds by screening with synthesized oligonucleotide probes based on partial amino acid sequences of oryzacystatin. A nearly full-length cDNA clone was obtained which encoded 102-amino acid residues. The amino acid sequence of oryzacystatin deduced from the cDNA ...

Bivalent DNA Vaccination with Genes Encoding Leishmania major Cysteine Proteinases Type I and II Protects Mice Against Infectious Challenge

Structure/function analysis of human cystatin SN and comparison of the cysteine proteinase inhibitory profiles of human cystatins C and SN.

Cystatins are reversible, competitive inhibitors of cysteine proteinases. Their inhibitory profiles, as well as their affinities for target enzymes, vary with different cysteine proteinases. Human cystatin C and salivary cystatin SN are 120- and 121-amino-acid (a.a.) proteins, respectively, and both contain 2 disulfide bonds. In this study, we examined the structure/function relationship of cys...

Interaction of recombinant human cystatin C with the cysteine proteinases papain and actinidin.

The interaction between recombinant human cystatin C and the cysteine proteinases papain and actinidin was studied by spectroscopic, kinetic and equilibrium methods. The absorption, near-u.v.c.d. and fluorescence-emission difference spectra for the cystatin C-proteinase interactions were all found to be similar to the corresponding spectra for chicken cystatin. The kinetics of binding of cystat...

کلون سازی cDNA سیستاتین ذرت (CCs)، و ارزیابی اثر بازدارندگی پروتئین آن در شرایط آزمایشگاهی

Isolating and cloning of plant protease inhibitor (PIs) genes and transforming them to the genome of other plants have paved the way for producing resistant transgenic plants against pests. Knowing that cystatins act as inhibitor factor against cysteine protease, short and long cystatin genes were isolated from maize mRNA. By using specific primers, cDNA of these genes were constructed and cl...
