mutation diminishes the decarboxylation activity to aspartate with no major effect on its activity to cysteine sulfinic acid. Mutation leads to increase in the zwitterion form of the internal aldimine tautomer
V81L/F240S/I250S/D266L
generation of mutant Undec1A-1180 by random mutagenxadesis through sequential error-prone PCR from a mutagenesis library. The mutant has 5.62fold highxader specific activity than wild-type Undec1A at 35°C and pH 7.0. The optimum pH of Undec1A-1180 does not change. Molecular docking results indicatxade that amino acid residues Ala235, Val237, Asp239, Ile267, Ala268, and Lys298 in mutant Unxaddec1A-1180 protein help recognize substrate molecules and catalyze the reaction with of L-cysteine sulfinic acid.
