First claim

Opening claim text (preview).

What is claimed is: 1. An engineered polypeptide having imine reductase activity and comprising an amino acid sequence with at least 90% sequence identity to the amino acid sequence of SEQ ID NO: 4, wherein the tyrosine at the position corresponding to amino acid 222 of SEQ ID NO: 4 is substituted with another amino acid in the sequence of the engineered polypeptide. 2. The engineered polypeptide of claim 1 , further comprising at least one substitution or substitution set as compared to the amino acid sequence of SEQ ID NO: 4, wherein the at least one substitution or substitution set is at one or more positions selected from 29/94/184/223/232/288/293, 29/94/184/232/287/288/293/311, 29/94/184/232/287/288/311, 29/94/184/232/287/293/332, 29/94/184/232/288/293/311/324/353, 29/94/184/232/288/311/324/332, 29/94/184/232/293, 29/94/184/232/311, 29/94/184/287/293, 29/94/184/287/293/311/353, 29/94/184/287/311, 29/94/184/288/293/324, 29/94/184/288/293/332/353, 29/94/184/288/298/332, 29/94/184/288/353, 29/94/184/293/311, 29/94/184/324, 29/94/223/232/287, 29/94/223/232/293/311/324, 29/94/223/288/293, 29/94/232/287/288/311, 29/94/232/288/293, 29/94/287/288/293, 29/94/287/288/293/353, 29/94/287/311, 29/94/293/311/324, 29/94/293/332/353, 29/94/311, 29/94/324/353, 29/184, 29/184/223/288/293/324, 29/184/232/288, 29/184/287, 29/184/287/288/293, 29/184/287/288/293/311, 29/184/287/311/332, 29/184/288/293, 29/184/288/293/311, 29/184/293, 29/184/293/311, 29/184/293/324, 29/184/353, 29/223/287/288/293/353, 29/232/287/288/293/332/353, 29/287/288/293, 29/287/288/293/324/353, 29/288/293, 29/311, 29/311/332, 29/353, 72/94/184/288/311, 86, 94/96/223/287/288/293/311/324/332, 94/99/184/293/311/332/353, 94/184/223, 94/184/223/232/287/311, 94/184/223/288/293, 94/184/223/293, 94/184/232/287/288, 94/184/232/287/288/324/332, 94/184/232/287/293, 94/184/232/287/293/332, 94/184/287/288/293, 94/184/287/288/311, 94/184/287/293/311/324/353, 94/184/287/311, 94/184/287/353, 94/184/288/293, 94/184/288/293/311, 94/184/288/293/311/332, 94/184/293, 94/184/293/311, 94/184/293/332/353, 94/223/232/311/353/355/356/357/358/359, 94/223/287/288/293, 94/223/288/293/311, 94/232/287/288/293/353, 94/232/288/293/353, 94/232/293, 94/232/293/324/332, 94/232/311, 94/287/288/293, 94/287/288/311/324, 94/288/293, 94/288/293/324, 94/293/324, 94/311/324, 153, 184/223, 184/223/287/288/353, 184/232/287/288/293/311, 184/232/287/288/324/353, 184/232/287/293/332, 184/287/288, 184/287/288/293, 184/287/288/293/324/353, 184/287/293, 184/287/293/311, 184/288/293/311/324, 184/332/353, 205, 223/232/287/288/332/353, 223/287/288, 223/287/288/293/311, 223/287/311/353, 223/288/293, 232/287/288/293, 232/287/288/293/311, 232/287/288/293/321, 232/287/311, 232/288/293, 232/288/293/332, 234/287/288/293/311, 287/288/293, 287/288/311/324, 287/293, 287/311, 287/311/332, 287/324, 288/293, 288/293/311/324/353, 288/293/324, 293/311, and 311/332. 3.
