2-phenylethanol biosynthesis
WikiPathways:WP5587
2-phenylethanol biosynthesis in Saccharomyces cerevisiae places glucose, phosphoenolpyruvate, erythrose 4-phosphate, 3-deoxy-D-arabino-heptulosonic acid 7-phosphate, shikimate, chorismate, phenylalanine, and 2-phenylethanol in shikimate- and Ehrlich-route reactions in the WP5587 GPML diagram. The graph distinguishes reversible phenylalanine transamination, DAHP condensation and the connected phenylpyruvate-to-phenylacetaldehyde Ehrlich route; collapsed upstream branches represent multiple enzymatic steps.

- EDIT — Review complete causal graph against native sources and correct unsupported or omitted relationships
Grounded missing G6P, prephenate, phenylpyruvate and phenylacetaldehyde; restored the connected Ehrlich route. Merged duplicate DAHP condensation lines and preserved reversible transamination. Collapsed glycolysis/shikimate branches have component enables relationships, not single-enzyme catalysis claims. Every native record was inspected; see reports/causal-graph-diagram-review.json for native-object counts, exclusions and identity corrections. Semantic validation and native GraphId locator checks passed; authority snapshots and full corpus gates are coordinated separately.
