Porcine liver betaine-homocysteine methyltransferase (BHMT; EC) was purified to homogeneity, and the Michaelis constants for betaine, dimethylacetothetin, and L-homocysteine are 23, 155, and 32 μM, respectively. The maximum rate of catalysis is 47-fold greater using dimethylacetothetin as a methyl donor compared with betaine. Partial amino acid sequence of porcine BHMT was obtained, and inosine-containing redundant oligonucleotide primers were used to amplify an 815-base pair sequence of the… CONTINUE READING
