(-) Compounds

Molecule 1 - ACTINORHODIN POLYKETIDE SYNTHASE ACYL CARRIER PROTEIN
    Chains: A
    Engineered: YES
    Expression System: ESCHERICHIA COLI
    Expression System Strain: BL21
    Expression System Variant: DE3
    Expression System Vector: PET11C
    Gene: ACTI
    Mutation: YES
    Organism Scientific: STREPTOMYCES COELICOLOR
    Other Details: ACTINORHODIN ACYL CARRIER PROTEIN (ACT ACP) FROM S. COELICOLOR WAS HETEROLOGOUSLY OVEREXPRESSED IN ITS APO FORM IN E. COLI BL21 (DE3) CELLS. THESE CELLS CONTAINED THE PLASMID PET11C C17S ACT ACP (COURTESY OF DR. TOM NICHOLSON). THIS IPTG INDUCIBLE VECTOR IS BOTH EASIER TO USE AND MORE RELIABLE THAN THE HEAT INDUCIBLE PT7- 7 VERSION ORIGINALLY CONSTRUCTED. THE PROTEIN WAS MODIFIED TO THE HOLO FORM USING S. COELICOLOR ACPS AND ENZYME COA.
    Strain: A3(2)
    Synonym: ACP, ACTI ORF3
