Rosmarinic acid portable pathway

Rosmarinic acid pathway definition imported from the 2026-05-17 portable BLAST/HMM package.

Representative Rosmarinic Acid Reaction Route
Phenylalanine donor branch plus tyrosine acceptor branch. This pathway merges two aromatic amino-acid branches; after RAS condensation, CYP98A-type hydroxylases form rosmarinic acid with CPR electron-transfer support. The page displays annotatable members in the current reference library.

Phenylalanine Donor Branch
01
Substrate
L-Phenylalanine
C9H11NO2
C6H5-CH2-CH(NH2)-COOH
Deamination into the phenylpropanoid donor branch
Product
trans-Cinnamic acid
C9H8O2
C6H5-CH=CH-COOH
PAL converts L-phenylalanine to cinnamate as the entry step toward the 4-coumaroyl-CoA donor.
02
Substrate
trans-Cinnamic acid
C9H8O2
C6H5-CH=CH-COOH
Cinnamate 4-hydroxylation
Product
4-Coumaric acid
C9H8O3
4-HO-C6H4-CH=CH-COOH
C4H/CYP73A forms 4-coumaric acid for downstream CoA activation.
03
Substrate
4-Coumaric acid
C9H8O3
4-HO-C6H4-CH=CH-COOH
Substrate
CoA
C21H36N7O16P3S
CoA-SH
CoA ligation to form the RAS acyl donor
Product
4-Coumaroyl-CoA
C30H38N7O18P3S
4-HO-C6H4-CH=CH-C(=O)-SCoA
4CL generates 4-coumaroyl-CoA as the acyl donor for the RAS condensation reaction.
Tyrosine Acceptor Branch And Condensation
04
Substrate
L-Tyrosine
C9H11NO3
4-HO-C6H4-CH2-CH(NH2)-COOH
Transamination to 4-hydroxyphenylpyruvate
Product
4-Hydroxyphenylpyruvate
C9H8O4
4-HO-C6H4-CH2-C(=O)-COOH
TAT routes L-tyrosine into the 4-hydroxyphenylpyruvate acceptor branch.
05
Substrate
4-Hydroxyphenylpyruvate
C9H8O4
4-HO-C6H4-CH2-C(=O)-COOH
Reduction to the HPLA acceptor
Product
4-Hydroxyphenyllactate
C9H10O4
4-HO-C6H4-CH2-CH(OH)-COOH
HPPR reduces 4-hydroxyphenylpyruvate to 4-hydroxyphenyllactate.
06
Substrate
4-Coumaroyl-CoA
C30H38N7O18P3S
4-HO-C6H4-CH=CH-C(=O)-SCoA
Substrate
4-Hydroxyphenyllactate
C9H10O4
4-HO-C6H4-CH2-CH(OH)-COOH
Ester-forming condensation
Product
4-Coumaroyl-4'-hydroxyphenyllactate
C18H16O7
4-HO-C6H4-CH=CH-C(=O)-O-CH(COOH)-CH2-Ar-OH
RAS couples the acyl donor with the HPLA acceptor to form the direct rosmarinic-acid precursor.
07
Substrate
4-Coumaroyl-4'-hydroxyphenyllactate
C18H16O7
mono-catechol ester precursor
CYP98A14-type hydroxylation with CPR electron-transfer support
Product
Rosmarinic acid
C18H16O8
caffeoyl-O-3,4-dihydroxyphenyllactate
CYP98A14 or close CYP98A enzymes catalyse 3/3' hydroxylation; CPR in the current reference library represents electron-transfer support for this P450 reaction and should not be interpreted as CPR alone performing hydroxylation.
