Phthalic acid esters (PAEs) are a family of recalcitrant pollutants mainly used as plasticizer. The strain Gordonia sp.YC-JH1, isolated from petroleum-contaminated soil, is capable of efficiently degrading a wide range of PAEs. In order to pertinently investigate the genetic mechanisms of PAEs catabolism by strain YC-JH1, its complete genome sequencing has been performed by SMRT sequencing technology. The genome comprises a circular chromosome and a plasmid with a size of 4,101,557 bp and 91,767 bp respectively. Based on the genome sequence, 3563 protein-coding genes are predicted, of which the genes responsible for PAEs degradation are identified, including the two genes of PAEs hydrolase and the gene clusters for phthalic acid and protocatechuic acid degradation. The genome information provides genomic basis of PAEs degradation to allow the complete metabolism of PAEs. The wide substrate spectrum and its genetic basis of this strain should expand its application potential for environments bioremediation, provide novel gene resources involved in PAEs degradation for biotechnology and gene engineering, and contribute to shed light on the mechanism of PAEs metabolism.

A coordinated effort of researchers to map (CHROMOSOME MAPPING) and sequence (SEQUENCE ANALYSIS, DNA) the human GENOME.
Short tracts of DNA sequence that are used as landmarks in GENOME mapping. In most instances, 200 to 500 base pairs of sequence define a Sequence Tagged Site (STS) that is operationally unique in the human genome (i.e., can be specifically detected by the polymerase chain reaction in the presence of all other genomic sequences). The overwhelming advantage of STSs over mapping landmarks defined in other ways is that the means of testing for the presence of a particular STS can be completely described as information in a database.
Techniques to determine the entire sequence of the GENOME of an organism or individual.
The parts of a GENOME sequence that are involved with the different functions or properties of genomes as a whole as opposed to those of individual GENES.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
