 Streptomyces sahachiroi 5-methyl-1-naphthoate + 6 CoA + 5 CO2 + 4 H2O + 3 NADP+ incubation of substrates with isoform AziB alone leads to a truncated single-ring product, 2-methylbenzoic acid. Presence of thioesterase AziG acting as a chain elongation and cyclization domain is required for additional two rounds of chain extension to form the expected product, 5-methyl-1-naphthoate. None of the other thioesterase domains (AziA6, AziA7, AziA8) are capable of catalyzing the reaction ?
