Oxidation of d - and l -Valine by Enzymes of Pseudomonas aeruginosa

Oxidation of D- and L-valine by enzymes of Pseudomonas aeruginosa.

Norton, J. E. (University of Oklahoma School of Medicine, Oklahoma City), and J. R. Sokatch. Oxidation of d- and l-valine by enzymes of Pseudomonas aeruginosa. J. Bacteriol. 92:116-120. 1966.-Cell-free extracts prepared from Pseudomonas aeruginosa grown on dl-valine catalyzed the consumption of oxygen with several d-amino acids, but not with the corresponding l-amino acids. The product of d-val...

Growth inhibition of Pseudomonas aeruginosa by valine.

determination of olanzapine and thiourea using electrodes modified by dna and film of copper-cobalt hexacyanoferrate & investigation of electro-oxidation of some catechol derivatives in the presence of 4-phenylsemicarbazid

چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...

Oxidation of methylmalonate semialdehyde to propionyl coenzyme A in Pseudomonas aeruginosa grown on valine.

The conversion of methyhnalonate semialdehyde to propionyl coenzyme A has been investigated with enzyme preparations made from Pseudomonas aeruginosa grown on valine. A protein fraction has been obtained which catalyzes the oxidation of methylmalonate semialdehyde, acetaldehyde, and propionaldehyde with NAD as the electron acceptor. The product of methyhnalonate semialdehyde oxidation in the pr...

Catabolism of L-lysine by Pseudomonas aeruginosa.

Pseudomonas aeruginosa PACI grows poorly on L-lysine as sole source of carbon but mutant derivatives which grow rapidly were readily isolated. Studies with one such mutant, P. aeruginosa PAC586, supported the existence of a route for L-lysine catabolism which differes from those reported previously in other species of Pseudomonas. The postulated route, the cadaverine or decarboxylase pathway, i...
