Fig. 1From: Identification of bacterial laccase cueO mutation from the metagenome of chemical plant sludge cueO mutants cloned from the soil metagenome. cueO is the wild-type gene. M-1, M-2, M-3, M-4, M-5, and M-6 represent the different mutants. These genes were amplified by the primers cueO-F and cueO-R, and gene mutants are shown by vertical barsBack to article page
