Abstract

Official abstract text for this publication.

The present application provides engineered polypeptides having imine or oxime reductase activity, polynucleotides encoding the engineered polypeptides, host cells capable of expressing the engineered polypeptides, and methods of using these engineered polypeptides with a range of ketone amine substrate compounds to prepare secondary and tertiary amine product compounds.

First claim

Opening claim text (preview).

What is claimed is: 1. An engineered polypeptide comprising an amino acid sequence with at least 80% sequence identity to a reference sequence of SEQ ID NO: 14, and wherein said engineered polypeptide has imine reductase activity. 2. The engineered polypeptide of claim 1 , wherein said polypeptide further comprises at least one substitution selected from 57T/211L, 87S/175G, 103H/212C, 122E, 123G, 124A/178I, 124G, 132H/R, 134R, 171W, 173H/I, 175G/H, 176S, 178I/242Y, 178M, 211L/W, 212C/G/V, 213P/R/T/V, 214M, 215L/M, 217I/L, 234L, and 235K, wherein said positions are numbered with reference to SEQ ID NO:2. 3. The engineered polypeptide of claim 1 , wherein said polypeptide further comprises at least one substitution selected from A57T/I211L, P87S/M175G, R103H/E212C, L122E, T123G, I124A/V178I, I124G, E132H/R, T134R, Y171W, A173H/I, M175G/H, L176S, V178I/A242Y, V178M, I211L/W, E212C/G/V, A213P/R/T/V, V214M, T215L/M, W217I/L, D234L, and A235K, wherein said positions are numbered with reference to SEQ ID NO:2. 4. The engineered polypeptide of claim 1 , wherein said polypeptide comprises an amino acid sequence with at least 80% sequence identity to any even-numbered sequence set forth in SEQ ID NO:4 to SEQ ID NO:74. 5. A method of producing an engineered imine or oxime reductase polypeptide, comprising the steps of culturing a host cell, under conditions such that an engineered polynucleotide is expressed and said engineered polypeptide of claim 1 is produced. 6. The method of claim 5 , further comprising the step of recovering said engineered polypeptide.
