G12, Polymerase Chain Reaction (PCR) experiments were performed using Streptomyces sp. G12 genomic DNA as template and degenerate and specific oligonucleotide primers reported in Table 1: central region was amplified with the oligonucleotides 1 FW/1 REV, the 5’ terminal region with the oligonucleotides 2 FW/2 REV, the 3’ terminal region with the oligonucleotides 3 FW/3 REV and their sequencing by dideoxy chain termination method was performed by PRIMM Sequencing Service (Naples, Italy), using universal and specific oligonucleotide primers.
