BACKGROUND Turmeric rhizome (Curcuma domestica Linn.) contains proteases and has proteolytic activity. Curcumin from turmeric rhizomes has been used for healing many ailments, including cancer. The purpose of this study was to purify turmeric protease and to research their biochemical

Protease mediated proteolysis has been widely implicated in virulence of necrotrophic fungal pathogens. This is counteracted in plants by evolving new and effective antimicrobial peptides (AMP) that constitute important components of innate immune system. Peptide extraction from rhizome of Zingiber

Unusually stable proteins are a disadvantage for the metabolic turnover of proteins in cells. The CutA1 proteins from Pyrococcus horikoshii and from Oryza sativa (OsCutA1) have unusually high denaturation temperatures (Td) of nearly 150 and 100 °C, respectively, at pH 7.0. It seemed that the CutA1

The current study was carried out to evaluate the pharmacological properties of cupincin- A novel cupin domain containing metalloprotease with limited proteolysis from rice bran on blood coagulation and hydrolysis of human fibrinogen. Cupincin preferentially hydrolyzed the Aα chain of fibrinogen and

The Asian rice gall midge, Orseolia oryzae (Wood-Mason), is a serious pest of rice. Investigations into the gall midge-rice interaction will unveil the underlying molecular mechanisms which, in turn, can be used as a tool to assist in developing suitable integrated pest management strategies. The

The complete nucleotide sequences of a cDNA (RSP1) that encodes a subtilisin-like serine protease (subtilase) of rice (Oryza sativa L.) and a gene (ASP48) for Arabidopsis subtilase were analyzed. The RSPI cDNA and ASP48 DNA encoded 736- and 757-residue pre-pro-polypeptides including a signal peptide

UNASSIGNED Our results suggest that a rice E3 ligase, OsMAR1, physically interacts with a cytosolic protein OCPI2 and may play an important role under salinity stress. Salt is an important abiotic stressor that negatively affects plant growth phases and alters development. Herein, we found that a

Although the possible cellular roles of several ubiquitin-specific proteases (UBPs) were identified in Arabidopsis, almost nothing is known about UBP homologs in rice, a monocot model plant. In this report, we searched the rice genome database ( http://signal.salk.edu/cgi-bin/RiceGE ) and identified

The ubiquitin C-terminal hydrolase (UCH) and ubiquitin-specific processing protease (UBP) protein families both function in protein deubiquitination, playing important roles in a wide range of biological processes in animals, fungi, and plants. Little is known about the functions of these proteins

Cupin superfamily is one of the most diverse super families. This study reports the purification and characterization of a novel cupin domain containing protease from rice bran for the first time. Hypothetical protein OsI_13867 was identified and named as cupincin. Cupincin was purified to 4.4 folds

Protease activities and its relation to the contents of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and Rubisco activase were investigated in detached leaves of rice (Oryza sativa L.) floated on the solutions containing abscisic acid (ABA) or benzyladenine (BA). Rubisco and Rubisco

The ATP-dependent Lon protease is a highly conserved enzyme that is present in archeae, eubacteria, and eukaryotes, and plays an important role in intracellular protein degradation. We have isolated a Lon protease gene, OsLon1, from Oryza sativa. The cDNA contained a 2,655 bp ORF. Comparative

In this study, we synthesized a synthetic serine proteinase inhibitor II gene (sPI-II) that harbored the chymotrypsin and trypsin inhibitor domains of the PI-II gene from Nicotiana alata. In an effort to reduce protease activity in a rice cell suspension culture, we first synthesized sPI-II using

BACKGROUND Proteases hydrolyse storage proteins to provide precursors for perpetuating species. The aim of this study was to investigate and characterise different proteases in germinating brown rice. RESULTS The protease activity of brown rice increased sevenfold during 7 days of germination. It

Plants lack aspartate-specific cell death proteases homologous to animal caspases. Instead, a subtilisin-like serine-dependent plant protease named phytaspase shown to be involved in the accomplishment of programmed death of plant cells is able to hydrolyze a number of peptide-based caspase
