A graphene nanosheets (GNS) film coated glassy carbon electrode (GCE) was fabricated for sensitive determination of tyrosine (Tyr). The GNS-based sensor was characterized by scanning electron microscope and electrochemical impedance spectroscopy. The voltammetric techniques were employed to study electro-oxidation of Tyr. The results revealed that the modified electrode showed an electrocatalyt...

Reversible protein phosphorylation is a widespread post-translational modification fundamental for signaling across all domains of life. Tyrosine (Tyr) has recently emerged as being important plant receptor kinase (RK)-mediated signaling, particularly during immunity. How Tyr regulates RK function however largely unknown. Notably, the expansion phosphatase and SH2 domain-containing families, wh...

A unique poly(amido amine) (PAMAM)/polymer dots (Pdots)/NiO heterostructure is developed for photocathodic detection of tyrosinase (TYR), which applicable to TYR in actual human serum samples.

Science the biological activities of chiral enantiomers are often different or even opposite, their recognition is great significance. A new assembly structure named TCPP-Zn-(S)-BINOL was obtained based on interaction between binaphthol (BINOL) and porphyrin-based MOF formed by Meso-Tetra(4-carboxyphenyl)porphine (TCPP) Zn2+, a sensor designed relying TCPP-Zn-(S)-BINOL. The platform using as re...

introduction oculocutaneous albinism (oca) is a genetically heterogeneous autosomal recessive genetic disorder that is characterized by reduced or completely absent pigmentation in the hair, skin, and eyes. conclusions a novel homozygous mutation, the deletion of exons 1 - 5 on the tyr gene, was found on the molecular genetic testing of this patient. exon 1 - 5 deletion on tyr causes a lack of ...
