Since growth experiments with various nitrogen and carbon sources (including L-serine) reveal no difference between the Pseudomonas aeruginosa wild-type and PA0743 deletion strains, it is suggested hat this organism might contain other (complementing) serine dehydrogenases Pseudomonas aeruginosa ? - ? 188041 1.1.1.387 L-serine + NAD+ the enzyme might be involved in serine/methylserine degradation.
