FIGURE 2.
Open reading frames identified in the asu cluster. The putative genes were divided into eight groups based on the functional characterization. Group A, 3,4-AHBA biosynthesis and adenylation; Group B, CHC-CoA biosynthesis; Group C, polyketide chain assembly; Group D, C5N moiety biosynthesis; Group E, oxygenation; Group R, transcriptional regulation. AsuM1, efflux protein. The relative genomic regions and overlapping inserts of three cosmid clones, 2B9, 10D6, and pART1391, are indicated with bold lines.
