in two separate studies a bcli-generated dna fragment coding for the enzyme tyrosinase , responsible for melanin synthesis , was cloned from streptomyces antibioticus dna into two slp1.2-based plasmid vectors ( pij37 and pij41 ) to generate the hybrid plasmids , designated pij700 and pij701 , using s. lividans 66 as the host .
