Nitrilase-Catalyzed Production of Nicotinic Acid from 3-Cyanopyridine in Rhodococcus rhodochrous J1.
The nitrilase which occurs abundantly in cells of Rhodococcus rhodochrous J1 catalyzes the direct hydrolysis of 3-cyanopyridine to nicotinic acid without forming nicotinamide. By using resting cells, the reaction conditions for nicotinic acid production were optimized. Under the optimum conditions, 100% of the added 3-cyanopyridine could be converted to nicotinic acid, the highest yield achieve...
متن کاملNitrilase-catalyzed production of pyrazinoic acid, an antimycobacterial agent, from cyanopyrazine by resting cells of Rhodococcus rhodochrous J1.
Using resting cells of Rhodococcus rhodochrous J1, in which a large amount of nitrilase is induced, a simple and efficient bioconversion process for the production of pyrazinoic acid, an antimycobacterial agent, through catalysis by a nitrilase was developed. The reaction conditions for production of pyrazinoic acid were optimized. Under optimum conditions, 3.5 M cyanopyrazine was converted to ...
متن کاملOverexpression and characterization of two types of nitrile hydratases from Rhodococcus rhodochrous J1
Nitrile hydratase (NHase) from Rhodococcus rhodochrous J1 is widely used for industrial production of acrylamide and nicotinamide. However, the two types of NHases (L-NHase and H-NHase) from R. rhodochrous J1 were only slightly expressed in E. coli by routine methods, which limits the comprehensive and systematic characterization of the enzyme properties. We successfully expressed the two types...
متن کاملMetabolism of 2-mercaptobenzothiazole by Rhodococcus rhodochrous.
2-Mercaptobenzothiazole, which is mainly used in the rubber industry as a vulcanization accelerator, is very toxic and is considered to be recalcitrant. We show here for the first time that it can be biotransformed and partially mineralized by a pure-culture bacterial strain of Rhodococcus rhodochrous. Three metabolites, among four detected, were identified.
متن کاملDraft genome sequence of Rhodococcus rhodochrous strain ATCC 17895
Rhodococcus rhodochrous ATCC 17895 possesses an array of mono- and dioxygenases, as well as hydratases, which makes it an interesting organism for biocatalysis. R. rhodochrous is a Gram-positive aerobic bacterium with a rod-like morphology. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 6,869,887 bp long genome contains 6,609 prote...
