Gamma-Butyrobetaine Hydroxylase Originated From Neurospora Crassa

摘要

Disclosed is a polynucleotide encoding gamma-butyrobetaine hydroxylase (gamma-BBH) originating from Neurospora crassa. Also disclosed are a recombinant vector comprising the polynucleotide, a transformant transformed with the recombinant vector, gamma-BBH encoded by the polynucleotide, and a method of preparing L-carnitine, which comprises hydroxylating gamma-butyrobetaine using gamma-BBH encoded by the polynucleotide.
