Abstract
Provided are non-natural or variant β-ketoacyl-acyl carrier protein (ACP) synthase (KAS) IVa enzymes (KASIVa), polynucleotides encoding such variant KASIVa, host cells expressing such variant KASIVa, oils and oil products produced by such cells, and methods of making and using such variant KASIVa.
Claims21
A polynucleotide encoding a β-ketoacyl-acyl carrier protein (ACP) synthase (KAS) IVa enzyme (KASIVa) variant, wherein the KASIVa variant comprises at least about 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identity to amino acid residues 34-523 of SEQ ID NO:
- 4 and comprises an X at the position corresponding to position 146;
- wherein X is an amino acid residue selected from the group consisting of glycine (G) and serine(S), wherein the position is with reference to SEQ ID NO:
- 4, and wherein the KASIVa variant catalyzes the elongation of a medium-chain fatty acyl-ACP.
