Tryptophan Catabolism: Identification and Characterization of a New Degradative Pathway

Tryptophan catabolism: identification and characterization of a new degradative pathway.

A new tryptophan catabolic pathway is characterized from Burkholderia cepacia J2315. In this pathway, tryptophan is converted to 2-amino-3-carboxymuconate semialdehyde, which is enzymatically degraded to pyruvate and acetate via the intermediates 2-aminomuconate and 4-oxalocrotonate. This pathway differs from the proposed mammalian pathway which converts 2-aminomuconate to 2-ketoadipate and, ul...

synthesis and characterization of some new cyclometalated organoplatinum(ii) complexes containing phosphite ligand

در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین (ii) حاوی لیگاند های دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)،trans/cis- [ptcl2(sme2)2] ، با 2 اکی مولار از لیگاند p(oph)3در حلال بنزن کمپلکس1، cis-[ptcl2(p(oph)3)2] را تولید می نماید. جهت سنتز کمپلکس سایکلو متال فسفیتی، کمپلکس 1 با 1 اکی والان واکنشگر ptcl2 در حلال زایلن در شرایط رفلاکس زیر گاز آرگون م...

Threonine dehydrogenase is a minor degradative pathway of threonine catabolism in adult humans.

The threonine dehydrogenase (TDG) pathway is a significant route of threonine degradation, yielding glycine in experimental animals, but has not been accurately quantitated in humans. Therefore, the effect of a large excess of dietary threonine, given either as free amino acid (+Thr) or as a constituent of protein (+P-Thr), on threonine catabolism to CO(2) and to glycine was studied in six heal...
