1.1.1.343 | malfunction | compared to the wild type, the deletion mutant strain DELTAgndA does not grow, but growth is fully recovered by in-trans complementation with gndA. Growth of the deletion mutant can also be recovered by the addition of uridine to the medium, suggesting that Haloferax volcanii can circumvent the metabolic block for pentose phosphate formation via the oxidative pentose phosphate pathway by converting uridine to ribose-5-phosphate, catalyzed by uridine phosphorylase and phosphopentomutase | Haloferax volcanii |
