From: Genome mining for natural product biosynthetic gene clusters in the Subsection V cyanobacteria
Additional gene clusters identified from Subsection V cyanobacterial genomes. a Hydrocarbon biosynthetic gene cluster identified from all the Subsection V cyanobacterial genomes. b Geosmin gene cluster identified from W. intricata UH strain HT-29-1, H. welwitschii UH strain IC-52-3, Fischerella sp. PCC 9431 and F. muscicola SAG 1427–1. c Sesquiterpene gene cluster from Fischerella sp. JSC-11, F. thermalis PCC 7521, F. muscicola PCC 7414and Fischerella sp. PCC 9605. d Sesquiterpene gene cluster with hypothetical protein instead of cytochrome p450 identified from Fischerella sp. PCC 9339, W. intricata UH strain HT-29-1, H. welwitschii UH strain IC-52-3 and Fischerella sp. PCC 9431. e Squalene gene cluster encoding phytoene desaturase identified in all Subsection V cyanobacterial genomes. f Squalene gene cluster encoding squalene hopene cyclase identified in all Subsection V cyanobacterial genomes except M. testarum BC008 and M. repens PCC 10914. g Squalene gene cluster encoding squalene hopene and hopene-assocciated glycosyltransferase identified in Chlorogloeopsis sp. PCC 9212, C. fritschii PCC 6912 and M. repens PCC 10914 (squalene synthase gene not clustered in M. repens PCC 10914). h) Unique squalene gene cluster identified from M. testarum BC008 genome. i) Chemical structures of heptadecane, geosmin, 8a-epi-selinene and squalene
