petrobactin biosynthesis
MetaCyc:PWY-6289
Complete ten-transformation native pathway including 3-dehydroshikimate conversion, carrier maturation and both convergent citrate/spermidine assembly branches. The organism context is Bacillus anthracis Sterne; the principal full pathway study used Sterne 34F2-derived preparations. The six versioned source proteins preserve native identities; current reviewed AsbB and AsbE annotations differ at their N termini, and exact tagged constructs are not equated to native sequences. Source-defined AsbF is dimeric; AsbB dimer evidence is retained on its functional role without assigning an unverified complex identity. The physiological catalyst of generic apo-to-holo carrier maturation remains unassigned. Generic carrier states represent whole chemical classes rather than full protein sequences. The authentic native reaction and CPD-9985 product are selected. Native and ChEBI:142778 have equal formula/charge but different spermidine-arm connectivity; no exact equation or product equivalence to RHEA:63821 is asserted. Its independently specified carrier side supports the holo output only. Both branches are supported by the primary in vitro study, while a unique intracellular order remains unresolved. AsbA partial substitution by AsbB and early free-aroylspermidine side products do not expand the selected native boundary. The inspected early-enzyme paper is abstract-only and the later study supplement was unavailable. The selected citryl intermediate identities leave absolute citrate-derived stereochemistry unspecified; they do not assert racemic physiology or acceptance of every stereoisomer.

Curation history
- codex
- CREATE — Prepare complete petrobactin biosynthesis from original evidence
Copy the full ten-transformation PWY-6289 route and both branches with versioned Sterne proteins, native product connectivity and explicit carrier/construct/source-access limitations. The initial author record, original source digests and independent review are preserved. Authority integration, final gates and publication remain pending.
- CREATE — Prepare complete petrobactin biosynthesis from original evidence
- codex
- EDIT — Correct AsbD protein participation description
Resolve the wording identified in the saved initial scientific review and issue388 by changing only edge082 description. The versioned protein is no longer called a generic carrier class; the final class non-equivalence qualification, all nodes, triples and evidence remain unchanged. Independent bounded correction acceptance passed; final integrated scientific disposition remains pending.
