| + | [https://www.uniprot.org/uniprot/PCHE_PSEAE PCHE_PSEAE] Involved in the biosynthesis of the siderophore pyochelin (PubMed:9846750, PubMed:11208777). Accepts salicylate activated by PchD at the first peptidyl carrier domain (ArCP), and activates and fixes one molecule of cysteine at the second peptidyl carrier domain (PCP1) via a thioester linkage to the phosphopanthetheine moiety (By similarity). Then catalyzes the condensation reaction between the salicylate bound to the first site and the cysteine bound to the second site, and the cyclization of the cysteine to form the salicyl-thiazolinyl-S-PCP1 intermediate at the second site (By similarity). When this intermediate is released by the action of a thioesterase, it produces the antifungal antibiotic dihydroaeruginoic acid (Dha or hydroxyphenyl-thiazolinyl-carboxylate) (PubMed:11208777).[UniProtKB:A0A0H2ZGB9]<ref>PMID:11208777</ref> <ref>PMID:9846750</ref> | ||
