Protein Variants

Protein Variants Comment Organism
D296Y naturally occurring mutation, the FdrAD296Y variant increases glyoxylate conversion to malate by accelerating oxamate production, which promotes carbon flow through the C4 branch, leading to increased succinate production Escherichia coli
additional information wild-type Escherichia coli is adapted to syntrophic growth with Methanobacterium formicicum for glycerol fermentation over 44 weeks leading to rapid evolution through repeated emergence of mutators that introduced a large number of nucleotide variants. Many mutators increase to high frequencies but remain polymorphic throughout the continuous cultivation. The evolved Escherichia coli populations exhibit gains both in fitness and succinate production, but only for growth under glycerol fermentation with Methanobacterium formicicum (laboratory conditions) and not under other growth conditions. Mutant alleles of the 69 single nucleotide polymorphisms (SNPs) are identified in the adapted Escherichia coli populations, analysis of phenotypic changes caused by 84 variants, including 15 nonsense variants, revealing that FdrAD296Y is the most significant variant leading to increased succinate production, overview Escherichia coli

General Information

General Information Comment Organism
metabolism the anaerobic allantoin degradation pathway involving the enzyme is linked to succinate production via the glyoxylate pathway during glycerol fermentation. Wild-type Escherichia coli is limited in producing succinate from glycerol as the sole carbon source under anaerobic conditions because it is energetically unfavorable, while Escherichia coli FdrAD296Y mutant increases glyoxylate conversion to malate by accelerating oxamate production, which promotes carbon flow through the C4 branch, leading to increased succinate production Escherichia coli
physiological function FdrA plays a crucial role in oxamate production. FdrA catalyzes a global prokaryote orphan reaction for anaerobic allantoin degradation, a model pathway through glyoxylate leading to succinate production under conditions of glycerol fermentation is presented Escherichia coli
