Integrated proteogenomics database

Bacteria iconB. henselae Houston-1

Bartonella henselae strain ATCC49882 (Houston-1; Genbank #NC_005956), isolated from an HIV-positive patient, is the reference strain [1].

An iPtgxDB was created by hierarchically integrating protein coding sequences from these annotation resources:

Hierarchy Resource Link
1 NCBI RefSeq 2015 GCA_000046705.1_ASM4670v1; from 07/30/2015
2 NCBI RefSeq 2013 Bartonella_henselae_Houston_1_uid57745; from 06/10/2013
3 Ensembl Ensembl's Genomes project (GCA_000046705.1, Feb/2015)
4 Genoscope [2] v2.7.3, accessed 03/09/2016
5 Prodigal [3] Ab initio gene predictions from Prodigal (v2.6)
6 ChemGenome [4] Ab initio gene predictions from ChemGenome (v2.0, http://www.scfbio-iitd.res.in/chemgenome/chemgenomenew.jsp; with parameters: method, Swissprot space; length threshold, 70 nt; initiation codons, ATG, CTG, TTG, GTG)
7 in silico ORFs The in silico ORF annotations were generated as described by Omasits and Varadarajan et al., 2017

Only ORFs above a selectable length threshold (here 18 aa) were considered. The iPtgxDB was created using the hierarchy RefSeq 2015 > RefSeq 2013 > Ensembl > Genoscope > ChemGenome > Prodigal > in silico. Files were parsed to extract the identifier, coordinates and sequences of bona fide protein-coding sequences (CDS) and pseudogene entries.
