Probing The Cob(Ii)Alamin Cond Uctorhhypothesis With Glutamate Mutase From Clostridium Cochlearium, Fe Lyatuu, A Parthasarathy, K Zhou, K Zelenka, Fh Zelder, W Buckel

Tanzania Journal of Science

It had been proposed that during reversible coenzyme B12 dependent rearrangements, cob(II)alamin is not merely present as a spectator but also acts as a conductor by stabilizing the methylene radical intermediates. Density functional theory (DFT) calculations suggested a hydrogen bond between C19-H of the corrin ring and the 3'-OH moiety (O3RL) of the 5'- deoxyadenosyl radical resulting in a decrease of the activation energy by about 30 kJ mol-1. We tested this hypothesis with glutamate mutase and artificial coenzyme B12 derivatives. The assembly of coenzyme B12 (adenosylcobalamin) with recombinant components GlmS and GlmE of glutamate mutase from Clostridium cochlearium reconstitutes …

Effects Of Temperature On The Physicochemical Properties Of Traditionally Processed Vegetable Oils And Their Blends, Fn Ngassapa, Ss Nyandoroa, Tr Mwaisaka Dec 2012

Effects Of Temperature On The Physicochemical Properties Of Traditionally Processed Vegetable Oils And Their Blends, Fn Ngassapa, Ss Nyandoroa, Tr Mwaisaka

Tanzania Journal of Science

The quality and stability of traditionally processed palm, sunflower and sesame oils and their blends as affected by temperature were evaluated by analyzing their physicochemical properties which included acid, saponification, peroxide, iodine values and refractive indices.. The initial quality of traditionally processed oils studied was found to be within the specifications of TZS and Codex requirements. The results further indicate that the quality of both unblended and blended traditionally processed vegetable oils deteriorate significantly at elevated temperatures (p < 0.05). However, the blends showed relatively better quality and stability than the unblended ones whereby the formulations of palm oil (PO) and sesame oil (SSO) appeared to be more stable than those of PO and sunflower oil (SO). This work suggests that blending of traditionally processed PO, SO and SSO improves the quality and stability of these oils.
