First Complete Genome Sequences of Janthinobacterium lividum EIF1 and EIF2 and their Comparative Genome Analysis

  • We present the first two complete genomes of the Janthinobacterium lividum species, namely strains EIF1 and EIF2, which both possess the ability to synthesize violacein. The violet pigment violacein is a secondary metabolite with antibacterial, antifungal, antiviral, and antitumoral properties. Both strains were isolated from environmental oligotrophic water ponds in Göttingen. The strains were phylogenetically classified by ANI analysis and showed a species assignment to Janthinobacterium lividum with 97.72% (EIF1) and 97.66% (EIF2) identity. These are the first complete genome sequences of strains belonging to the species Janthinobacterium lividum. The genome of strain EIF1 consists of one circular chromosome (6,373,589 bp) with a GC-content of 61.98%. The genome contains 5,551 coding sequences, 122 rRNAs, 93 tRNAs, and 1 tm-RNA. The genome of EIF2 comprises one circular chromosome (6,399,352 bp) with a GC-content of 61.63% and a circular plasmid p356839 (356,839 bp) with a GC-content of 57.21%.

In addition to the highly conserved chromosomally encoded violacein operon, the plasmid comprises a non-ribosomal peptide synthetase cluster (NRPS) with similarity to xenoamicin, which is a bioactive compound effective against protozoan parasites.show moreshow less
