Protein Variants

Protein Variants Comment Organism
A134F site-directed mutagenesis, the mutant has the same global architecture as wild-type enzyme, the mutant shows highly reduced activity with the majority of long-chain aldehyde substrates tested. the A134F variant displays an approximate fourfold increase in the rate of butanal consumption and approximately sixfold increase in pentanal consumption compared to wild-type enzyme, the mutant generates enhanced levels of propane production in whole-cell biotransformations compared to wild-type cADO Prochlorococcus marinus
additional information alteration of the enzyme's substrate specificity by engineering of active site residues involved in substrate binding, residues V41 and A134, adjacent to the C9 position of the ligand, might influence fatty acid binding, overview Prochlorococcus marinus
V41Y site-directed mutagenesis, the mutant has the same global architecture as wild-type enzyme, the mutant shows highly reduced activity with the majority of long-chain aldehyde substrates tested Prochlorococcus marinus
V41Y/A134F site-directed mutagenesis, the double mutant shows reduced activity with long-chain aldehyde substrates and increased activity with short-chain aldehyde substrates like the single mutants Prochlorococcus marinus

General Information

General Information Comment Organism
additional information the enzyme shows a mainly alpha helical architecture, with a ferritin-like four-helix bundle. The latter contains the di-iron centre, coordinated by two histidine residues and four carboxylates from glutamate side chains. Substrates access the active site through a tunnel-like hydrophobic pocket. Active site structure analysis from crystal structure, PDB ID 20C5 Prochlorococcus marinus
