Overall scheme of the biocatalytic production of gaseous hydrocarbons propane, isobutane and butane from amino acids valine, leucine and isoleucine, respectively. Enzymes: ilvE = leucine 2-oxoglutarate transaminase from E. coli; BCKDHAB = human branched-chain α-keto acid dehydrogenase complex; YciA = acyl-CoA thioester hydrolase from Haemophilus influenza; CAR = carboxylic acid reductase from Mycobacterium marinum; sfp = maturation factor phosphopantetheinyl transferase from Bacillus subtilis; CvFAP = fatty acid photodecarboxylase from Chlorella variabilis; ADO = aldehyde deformylating oxygenase from Prochlorococcus marinus; Ferr = ferredoxin from Synechocystis sp. PCC6803 and KdcA = branched-chain keto acid decarboxylase from Lactococcus lactis. AlDH enzymes: αKGSDH = α-ketoglutaric semialdehyde dehydrogenase from Burkholderia ambifaria; PadA = phenylacetaldehyde dehydrogenase 17 from E. coli; or Hpad = 3-hydroxypropionaldehyde dehydrogenase puuC from E. coli
