Cloning, expression, and enzymatic activity analysis of strawberry S-adenosyl-L-metnionine synthetase gene FaSAMS1

The S-adenosyl methionine synthetase gene FaSAMS1 is involved in the regulation of strawberry fruit ripening, however, the biochemical properties of FaSAMS1 protein remain unclear. Here, a coding cDNA sequence of FaSAMS1 was cloned by RT-PCR and inserted into a recombinant yeast expression vector pPICZA, then transformed into the yeast expression strain X-33.
