An Active-Site Bronsted Acid–Base Catalyst Destabilizes Mandelate Racemase and Related Subgroup Enzymes: Implications for Catalysis

H R Hemantha Kumar, Oliver P. Kuehm, Sarah A.E. Aboushawareb, Atieh Rafiei et autres

Enzymes of the enolase superfamily (ENS) are mechanistically diverse, yet share a common partial reaction, i.e., the metal-assisted, Bro̷nsted base-catalyzed abstraction of the α-proton from a carboxylate substrate to form an enol(ate) intermediate. Although the catalytic machinery responsible for the initial deprotonation …

Effects of enzymatic modification of milk proteins on flavour and textural qualities of set yoghurt

H R Hemantha Kumar, P Vincent Monteiro, Gajanan Bhat, H G Ramachandra Rao

Milk proteins were enzymatically modified, using neutrase and trypsin immobilised on CM-Sephadex C-50, to the extent of 3, 4 and 5% degrees of hydrolysis. The neutrase-treated milk and the trypsin-treated milk were used separately to prepare set yoghurt. The set yoghurt prepared …
