Biotechnology and Bioengineering, EarlyView.ABSTRACT Isobutanol is a fusel alcohol that can be produced microbially for use as a biofuel or upgraded into sustainable aviation fuel (SAF). A key enzyme in the isobutanol biosynthetic pathway is 2‐ketoacid decarboxylase (KDC), which irreversibly decarboxylates 2‐ketoisovalerate (KIV) to yield isobutyraldehyde.
