Regiospecific enzymatic oxygenation of cis-vaccenic acid in the marine phototrophic bacterium Erythrobacter sp. strain MG3
Original language description
The fatty acid composition of the marine phototrophic bacterium Erythrobacter sp. strain MG3 was analysed. The involvement of an unusual enzymatic peroxidation of the allylic carbon 10 of cis-vaccenic acid in this strain was confirmed. This process, which seems to be a characteristic of some aerobic and anaerobic phototrophic bacteria, appeared to also act on the allylic carbon 10 of octadeca-5,11-dienoic acid. Enzymatic degradation of 10- hydroperoxyoctadec-11(cis)-enoic acid resulting from the peroxidation of cis-vaccenic acid mainly involves reduction to the corresponding hydroxy acid (probably catalysed by peroxygenases) and cleavage to the corresponding oxoacid, which is then biohydrogenated

Regiospecifická enzymatická oxygenace kyseliny cis-vakcenové u mořské fototrofní bakterii Erytrobacter sp. kmen MG3
Czech description
Bylo analyzováno složení mastných kyselin u fototrofní bakterie Erythrobacter sp. kmen MG3. Byl nalezen neobvyklý mechanismus enzymatické peroxidace allylové skupiny kyseliny vakcenové. Tento proces je pravděpodobně charakteristický pro některé aerobní aanaerobní fototrofní bakterie. Enzym zpracovává též allylovou skupinu oktadeka-5,11-dienové kyseliny. Laboratorní experimenty prokázaly že rozsah této enzymatické peroxidace závisí na physiologickém stavu buněk a je zesílen při uhlíkové limitaci a nízkých teplotách
