Application

Application Comment Organism
synthesis contrary to wild-type MGA3 cells that secrete 0.4 g/l L-lysine and 59 g/l L-glutamate under optimised fed batch methanol fermentation, the hom-1 mutant M168-20 secretes 11 g/l L-lysine and 69 g/l of L-glutamate. Overproduction of pyruvate carboxylase and its mutant enzyme P455S in M168-20 has no positive effect on the volumetric L-lysine yield and the L-lysine yield on methanol, and causes significantly reduced volumetric L-glutamate yield and L-glutamate yield on methanol Bacillus methanolicus

Protein Variants

Protein Variants Comment Organism
additional information heterologous expression in a hom-negative Escherichia coli mutant Gif 102, not able to grow on minimal medium unless added 1.5 mM of both L-threonine and L-methionine results in strains growing well on minimal agar plates without added threonine and methionine Bacillus methanolicus
