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