NEW PLASMID pPS1M2 DERIVED FROM PSYCHROTROPHIC BACTERIUM AND DERIVATIVE THEREOF

摘要

PROBLEM TO BE SOLVED: To obtain a cyclic double-stranded DNA plasmid pPS1M2 separated from psychrotrophic bacterium and capable of efficiently producing a psychrotrophic enzyme, etc., in high yield by a genetic recombination technique by utilizing the cyclic double-stranded DNA plasmid pPS1M2 as a vector. SOLUTION: This cyclic double-stranded DNA plasmid pPS1M2 is characterized by having 3138 bp length and the restriction map shown by Fig. or its derivative.
