Schematic of the polyketide synthase (PKS) type III pathway discovered within the Mor1 genome using antiSMASH [41]. a The entire Mor1 type III PKS gene cluster with maroon genes corresponding to biosynthetic genes, green genes corresponding to regulatory genes, and grey genes corresponding to other uncharacterized genes. This locus is located between nucleotides 1238773 – 1279822 of the genome. b The comparison of the Mor1 gene cluster with homologous areas within the alkylresorcylic acid pathway gene cluster in the genome of Myxococcus xanthus DZF1. The red arrow corresponds to a stilbene synthase gene with 58 % identity and 99 % coverage; the green arrow corresponds to a methyltransferase gene with 54 % identity and 85 % coverage; the blue arrow corresponds to an AMP-dependent synthetase with 54 % identity and 96 % coverage; the yellow arrow corresponds to a monooxygenase gene with 47 % identity and 69 % coverage.
