Purification and characterization of a trypsin inhibitor from rice bran.

Properties of a Trypsin Inhibitor from Job’s-tears (Coix lacryma-jobiL. var.Ma-yuenStapf)

“…JBTI has a molecular weight of 12,201, whereas the molecular weight of rice bran trypsin inhibitor was reported to be 14,500. 8 ) Si.nce both rice and job's-tears are classified as Gramineae, there might be some reason that their trypsin inhibitors resemble each other.…”

Double-headed Nature of a Trypsin Inhibitor from Rice Bran

“…determined by SDSpolyacrylamide gel electrophoresis. 3 , This seems to be due to weak self-association of RBTI. However, no formation of the complexes like T2I2 or T4I2 was observed in this study.…”

“…Received December 3,1979 Cereal grains are rich sources of proteinase inhibitors and several trypsin inhibitors have been isolated and characterized l ) We have also reported the purification and characterization of a trypsin inhibitor from rice bran 2 . 3 ) The rice bran trypsin inhibitor (RBTI) is a basic protein with a molecular weight of 14,500 and its amino acid composition is similar to that of other trypsin inhibitors of cereal origin. With respect to inhibitory property, however, RBTI is distinct from these inhibitors.…”

Effects of Balancing Rice Bran Based Diets for Up to Four Amino Acids on Growth Performance of Broilers

“…Since the cost of formulations can substantially be reduced by increasing the level of RB in the diet, the actual feeding value of higher dietary RB levels should better be compared on gain per unit feed cost basis than on direct growth parameters such as weight gain and live weight. Availability of AAs from RB for poultry is low due to several reasons such as complexing with phytic acids (Ravindran et al 1995;Rutherford et al 1997;Selle et al 2000), negative effects of fibre (Warren and Farrell 1990) and anti-proteolytic substances (Kratzer and Chiaravanout 1974;Deolanker and Singh 1979;Tashiro and Maki 1979;. Mitsuda et al 1977 ).…”
