Mutational analysis of the coat protein N-terminal amino acids involved in potyvirus transmission by aphids.
The nature of the amino acids in the N-terminal 'DAGX' motif of the coat protein of tobacco vein mottling virus (TVMV) that have a direct effect on aphid transmissibility of the virion were further defined by site-directed mutagenesis. In the first position of the DAGX motif, Asp or Asn are required for aphid transmissibility. In the second position, the nonpolar residue Ala, but not the nonpol...
متن کاملThe Isolation of Amino Acids from Mixtures
1. The separation ofthe dinitrophenyl derivatives ofmethionine, leucine (together with isoleucine), phenylalanine, ornithine, lysine and tyrosine from each other, and from the dinitrophenyl derivatives of the other protein amino acids, by partition chromatography on columns is described. 2. The harmful effect on resolving power of using too close-fitting a packing tool in preparing these partit...
متن کاملEfflux of amino acids from the lens.
Estimation of efflux of amino acids from the viammalian lens indicates it is of small magnitude compared to influx at equivalent nonsaturating levels of substrate. This finding is a necessary part of the explanation of the complex problem of the maintenance of elevated, intracellular levels of these substances. Accelerative countertransport was observed when appropriate amino acids were present...
متن کاملEssential amino acids, from LUCA to LUCY
I n human dietary guides it is pointed out that 10 amino acids are essential and must be supplied in the diet. Since all 20 coded amino acids are required by every organism, we may assume that the remaining 10 are synthesized by human metabolism from other ingested molecules. Keeping the above in mind, let us consider the synthesis of amino acids in reductive chemoautotrophs, believed to be the...
متن کاملMycosporine-like amino acids from coral dinoflagellates.
Coral reefs are one of the most important marine ecosystems, providing habitat for approximately a quarter of all marine organisms. Within the foundation of this ecosystem, reef-building corals form mutualistic symbioses with unicellular photosynthetic dinoflagellates of the genus Symbiodinium. Exposure to UV radiation (UVR) (280 to 400 nm) especially when combined with thermal stress has been ...
