Provided are genetically engineered microorganism that catalyze the synthesis of propane and/or butanol from a suitable substrate such as glucose. Also provided are methods of engineering said genetically engineered microorganism and methods of producing propane and/or butanol using the genetically engineered microorganism.

A fatty acid decarboxylase is disclosed, the fatty acid decarboxylase comprising at least 40% sequence identity to SEQ ID NO:1 or 2, and an amino acid substitution at a position corresponding to G462 of SEQ ID NO:1.

Compositions and methods for producing aldehydes, alkanes, and alkenes are described herein. The aldehydes, alkanes, and alkenes can be used in biofuels.
