Complete nucleotide sequence of the 113-kilobase linear catabolic plasmid pAL1 of Arthrobacter nitroguajacolicus Ru61a and transcriptional analysis of genes involved in quinaldine degradation.

ABSTRACT: The nucleotide sequence of the linear catabolic plasmid pAL1 from the 2-methylquinoline (quinaldine)-degrading strain Arthrobacter nitroguajacolicus Rü61a comprises 112,992 bp. A total of 103 open reading frames (ORFs) were identified on pAL1, 49 of which had no annotatable function. The ORFs were assigned to the following functional groups: (i) catabolism of quinaldine and anthranilate, (ii) conjugation, and (iii) plasmid maintenance and DNA replication and repair. The genes for conversion of quinaldine to anthranilate are organized in two operons that include ORFs presumed to code for proteins involved in assembly of the quinaldine-4-oxidase holoenzyme, namely, a MobA-like putative molybdopterin cytosine dinucleotide synthase and an XdhC-like protein that could be required for insertion
