Enzymatic polymerization of enantiomeric L−3,4-dihydroxyphenylalanine into films with enhanced rigidity and stability

Nature Communications, 2023
L−3,4-dihydroxyphenylalanine is an important molecule in the adhesion of mussels, and as an oxidative precursor of natural melanin, it plays an important role in living system.

3,4-Dihydroxyphenylalanine and 5-Hydroxytryptophan as Reserpine Antagonists [PDF]

Nature, 1957
THE depletion by reserpine of storage in the body of 5-hydroxytryptamine (‘Serotonin’) and of the catechol amines is now well established1–3. In reserpinized animals the peripheral part of the adrenergic system does not function owing to lack of the transmitter2. This is presumably true also of the central part of the adrenergic system.

Directed evolution of an improved aminoacyl-tRNA synthetase for incorporation of L-3,4-dihydroxyphenylalanine (L-DOPA).

Angewandte Chemie, 2021
The catechol group of 3,4-dihydroxyphenylalanine (L-DOPA) derived from L-tyrosine oxidation is a key post-translational modification (PTM) in many protein biomaterials and has potential as a bioorthogonal handle for precision protein conjugation ...

Proximate composition and anti-nutritional factors in Mucuna pruriens (velvet bean) seed flour as affected by several processing methods

Heliyon, 2023
Mucuna pruriens seed being an underutilized legume with antinutrients was processed to reduce antinutrients and improve nutritional quality. The seeds were cleaned, washed and subjected to single treatments of soaking (24 h, 48 h, 72 h), cooking (20 min,

Beyond Melanin: Proteomics Reveals Virulence-Related Proteins in Paracoccidioides brasiliensis and Paracoccidioides lutzii Yeast Cells Grown in the Presence of L-Dihydroxyphenylalanine

Journal of Fungi, 2020
Species of the genus Paracoccidioides cause a systemic infection in human patients. Yeast cells of Paracoccidioides spp. produce melanin in the presence of L-dihydroxyphenylalanine and during infection, which may impact the pathogen’s survival in the ...
