ABSTRACT:
The present invention provides a novel gene encoding DNA sequence for the expression of parathion hydrolase and an analog thereof, and methods for preparing such compounds. In a particularly preferred embodiment, the present invention relates to a parathion hydrolase gene encoding sequence in which twenty-eight amino acids are deleted from the N-terminal amino acid sequence of parathion hydrolase. The novel gene encoding parathion hydrolase encoding sequence is useful for production of the mature or processed parathion hydrolase and a methionine (-1) analog thereof.
