Claims13
A method of producing adipate-semialdehyde comprising culturing a non-naturally occurring microorganism comprising at least one exogenous nucleic acid encoding an aldehyde dehydrogenase enzyme that reacts with adipyl-CoA to form adipate-semialdehyde, wherein
- the aldehyde dehydrogenase has greater catalytic efficiency for adipyl-CoA as a substrate as compared to succinyl-CoA, acetyl-CoA, or both as substrates, and/or
- the aldehyde dehydrogenase has higher turnover number for adipyl-CoA substrate as compared to succinyl-CoA, acetyl-CoA, or both succinyl-CoA and acetyl-CoA substrates
- and wherein the aldehyde dehydrogenase has at least 80%, at least 85%, at least 90%, at least 95%, at least 99%, or 100% amino acid sequence identity to any one of SEQ ID NOs:
- 4, 7, 11, 15, 17, 19, 24, 25, 27, 28, 31-33, 36, 38, 40-42, 44, 45, 47, 53, 58-60, 63, 65-67, 74, 75, 77, 80, 82, 84, 86-88, 90, 91, 94, 95, 97, 100, 101, 103, 107, 109, 111, 112, 117, 134, 135, 137, 145, 146, 148-150, 152, 157-159, 164-167, 176, 187, and 188.
