Cloned (Comment) Organism
PCR-amplificatioin, mariner plasmid Streptococcus pneumoniae D39

Protein Variants

Protein Variants Comment Organism
additional information no formate production and decrease of unsaturation index in downstream (in absence of acetate) fatty acid production in mutants SPD0420M (enzyme mutant) and SPD1774M (activating enzyme mutant), restored by complementation, increased survival and lower disease sign score of mice infected with mutant strains, wild-type survival rate in complemented mutants, lower nasopharynx numbers and lower survival in lungs, intravenous infection with similar growth of mutant and wild-type. All mutant and wild-type strains grow better under aerobic than anaerobic conditions with glucose as sole carbon source, no difference in growth rate and yields between mutants and wild-type, with galactose (generally lower growth rate than with glucose) as carbon source all but strain SPD1774M grow better under aerobic conditions, strain SPD1774M better under anaerobic conditions, strain SPD0420M has lower growth rate than wild-type under anaerobiosis, the complemented strain SPD0420Comp grows better than SPD0420M in anaerobiosis. Mutants SPD035M and SPD0229M do not affect pyruvate formate lyase dependent product formation. Streptococcus pneumoniae D39
