The aim of the present study was to utilize the protein from pigeon pea milling waste by-product for the preparation of protein isolate (PPI). The PPI was exposed to pepsin hydrolysis to reveal functional aspects like increased antioxidant capacity along with gelling ability. Complexation study demonstrated the use of PPI as an encapsulating material for water insoluble bioactive compounds (curcumin).

In mammalian cells, human 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), a rate-limiting endoplasmic reticulum (ER) bonded enzyme, plays a central role in the cholesterol homeostasis via the negative feedback mechanism. The present study indicates that the interactions of novel peptides with the catalytic domain of HMGCR, provides an alternative therapeutic candidate for reducing cholesterol. The potential natural origin of HMGCR peptide inhibitors were filtered from the peptide library using the molecular docking, which revealed three strong candidates for inhibition.

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 then the Bβ-chain, but not the γ-chain. Cupincin reduced the re-calcification time of citrated human plasma dose dependently.

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.

However its utility is limited due to the presence of lipase and lipoxygenase which initiates rancidity on milling. The aim of this investigation is to prevent oxidation of free fatty acids by enzymatic approach for its effective utilization.

The endoglucanase activity increased by 4-fold at 40% cosolvent concentration under optimum conditions. The endoglucanase lost 50% of its activity when exposed to 90 degrees C for more than 30 min (1 h).
