In this work, a redox-neutral, cell free enzymatic cascade was developed for the production of L‑alanine from commonly available D-glucose. Therefor, a variety of enzymes has been cloned, expressed and characterized under the desired cascade conditions. Optimization of the biocatalysts was done via directed evolution and rational protein design. Molecular dynamics analysis for the engineered aldehyde dehydrogenase from Thermoplasma acidophilum gave insights into improved kinetic parameters. Finally a fine tuning of the cascade parameters such as enzyme ratio and buffer concentration could further increase the economy of the designed process.
