CIDNP techniques were applied to the investigation of the elementary mechanism of photoinduced interaction between anti-arrhythmic drug lappaconitine and amino acids tyrosine and tryptophan. It has been shown that the reactions involve the formation of lappaconitine radical anion. Lappaconitine radical
Quinaldine catabolism was investigated with the bacterial strain Arthrobacter sp., which is able to grow aerobically in a mineral salt medium with quinaldine as sole source of carbon, nitrogen and energy. The following degradation products of quinaldine were isolated from

N-acetylanthranilate amidase (Amq), a 32.8-kDa monomeric amide hydrolase, is involved in quinaldine degradation by Arthrobacter nitroguajacolicus Rü61a. Sequence analysis and secondary structure predictions indicated that Amq is related to carboxylesterases and belongs to the alpha/beta-hydrolase-fold superfamily of enzymes; inactivation of
Arthrobacter nitroguajacolicus Rü61a, which utilizes quinaldine as sole source of carbon and energy, was shown to contain a conjugative linear plasmid of approximately 110 kb, named pAL1. It exhibits similarities with other linear plasmids from Actinomycetales in that it has
Applied and environmental microbiology, 80(23), 7266-7274 (2014-09-23)
A bacterial strain, which based on the sequences of its 16S rRNA, gyrB, catA, and qsdA genes, was identified as a Rhodococcus sp. closely related to Rhodococcus erythropolis, was isolated from soil by enrichment on the Pseudomonas quinolone signal [PQS;
