Abstract:
Helicobacter pylori is a human gastric pathogen infecting
almost half of the world population. Herein, we present an
updated version of the metabolic reconstruction of H. pylori
strain 26695 based on the revised genome annotation and new
experimental data. This reconstruction, iIT341 GSM/GPR,
represents a detailed review of the current literature about H.
pylori as it integrates biochemical and genomic data in a
comprehensive framework. In total, it accounts for 341
metabolic genes, 476 intracellular reactions, 78 exchange
reactions, and 485 metabolites. Novel features of iIT341
GSM/GPR include (i) gene-protein-reaction associations, (ii)
elementally and charge-balanced reactions, (iii) more accurate
descriptions of isoprenoid and lipopolysaccharide metabolism,
and (iv) quantitative assessments of the supporting data for
each reaction. This metabolic reconstruction was used to carry
out in silico deletion studies to identify essential and
conditionally essential genes in H. pylori. A total of 128
essential and 75 conditionally essential metabolic genes were
identified. Predicted growth phenotypes of single knockouts
were validated using published experimental data. In addition,
in silico double-deletion studies identified a total of 47
synthetic lethal mutants involving 67 different metabolic genes
in rich medium.
