Allgemeine Beschreibung

L-Tyrosine is an important amino acid mainly used as a dietary supplement.
L-tyrosine, an aromatic amino acid, is used common dietary supplement that has a wide range of applications in food and pharmaceutical industry. It is a precursor for preparing industrially important compounds such as 3,4-dihydroxy-L-phenylalanine (L-DOPA), melanin and p-hydroxystyrene. L-tyrosine can be synthesized by different biotechnological methods which are ecofriendly.

We present the development of a simple, high-throughput screen for identifying bacterial strains capable of L-tyrosine production. Through the introduction of a heterologous gene encoding a tyrosinase, we were able to link L-tyrosine production in Escherichia coli with the synthesis

Using quantum mechanics/molecular mechanics calculations and the 1.9-Å crystal structure of Photosystem II [Umena Y, Kawakami K, Shen J-R, Kamiya N (2011) Nature 473(7345):55-60], we investigated the H-bonding environment of the redox-active tyrosine D (TyrD) and obtained insights that help

The inflammasome adaptor ASC contributes to innate immunity through the activation of caspase-1. Here we found that signaling pathways dependent on the kinases Syk and Jnk were required for the activation of caspase-1 via the ASC-dependent inflammasomes NLRP3 and AIM2.

Low-grade gliomas (LGGs) may harbor malignant foci, which are characterized by increased tumor cellularity and angiogenesis. We used diffusion-weighted MR imaging (apparent diffusion coefficient [ADC]) and PET with the amino acid O-(2-(18)F-fluorethyl)-L-tyrosine ((18)F-FET) to search for focal changes of diffusion

The aromatic amino acid L-tyrosine is used as a dietary supplement and has promise as a valuable precursor compound for various industrial and pharmaceutical applications. In contrast to chemical production, biotechnological methods can produce L-tyrosine from biomass feedstocks under environmentally
