Tubulin-tyrosine ligase catalyzes covalent binding of 3-fluoro-tyrosine to tubulin: kinetic and [19F]NMR studies
The use of 3-fluoro-tyrosine as an alternative substrate for the enzyme tubulin:tyrosine ligase which catalyzes the incorporation of tyrosine into the α-tubulin subunit was investigated. The incorporation of tyrosine into ...
Peptide-based biomaterials. Linking l -tyrosine and poly l -tyrosine to graphene oxide nanoribbons
(Royal Society of Chemistry, 2015-03-31)
Peptide-based biomaterials are being studied actively in a variety of applications in materials science and biointerface engineering. Likewise, there has been ongoing exploration over the last few decades into the potential ...
Fabrication of a novel enzymatic electrochemical biosensor for determination of tyrosine in some food samples
(Elsevier Science, 2018-06)
In this work, fabrication of a novel and ultrasensitive electrochemical biosensor based on immobilization oftyrosine hydroxylase onto palladium-platinum bimetallic alloy nanoparticles/chitosan-1-ethyl-3-methylimidazolium ...
The tyrosine kinase FER is responsible for the capacitation-associated increase in tyrosine phosphorylation in murine sperm
(Company of Biologists, 2016-07)
Sperm capacitation is required for fertilization. At the molecular level, this process is associated with fast activation of protein kinase A. Downstream of this event, capacitating conditions lead to an increase in tyrosine ...
Oxidation of tyrosine: Antioxidant mechanism of L-DOPA disclosed
(Elsevier Science Inc., 2021-03)
Tyrosine is an amino acid related to crucial physiological events and its oxidation, that produce beneficial or detrimental effects on biological systems, has been extensively studied. Degradation of tyrosine often begins ...
Tyrosine oxidation and nitration in transmembrane peptides is connected to lipid peroxidation
(Elsevier Science Inc, 2017-05)
Tyrosine nitration is an oxidative post-translational modification that can occur in proteins associated to hydrophobic bio-structures such as membranes and lipoproteins. In this work, we have studied tyrosine nitration ...
