Article Title: Elucidating the taste profile in black tea through molecular docking and molecular sensory science.
Article Snippet: Crush-tear-curl (CTC) black tea is the largest global tea category by trade volume.. This study investigated the material basis for taste differences in CTC black tea through the analysis of electronic tongue, high-performance liquid chromatography, and high-speed amino acid analyzers.. Taste contributions were calculated using threshold values and dose-over-threshold calculations, then compounds were validated through recombination, addition, and omission experiments to confirm their contributions.

Article Snippet: Trm56 from Thermoplasma acidophilum is an exceptional SpoU-TrmD superfamily enzyme, which possesses an unusually long C-terminal region, and catalyzes methylation of 2 -OH of ribose of C56 in tRNA.. T. acidophilum Trm56 methylates elongator tRNA (tRNA e) transcript effectively, however this enzyme methylates tRNA transcript slowly.. This enzymatic feature is common in T. acidophilum Trm56 and Pyrococcus horikoshii Trm56, which possesses a short C-terminal region.

Binding model of CHE19 to the CHIKV spike protein. (A) Amino acid (aa) sequence alignment (1 to 300 aa) using Blosum62 for E2 (423 aa) from the CHIKV Thai#16856, Thai/ES245-7, Ross, and Thai E2 mutants. Domains of E2 determined from the crystal structure of the E2/E1 heterodimer (16) are shown. Domains A, B, and C are shown in black with underlining, while the N-linker segment and 2 β-ribbon connectors, β-ribbon (1) and β-ribbon (2) are shown in purple. The amino acid residues of Thai#16856 came into contact within 4 Å from the heavy atoms of the paratopes of the CHE19, as in panel A-2, are shown in red. The positions where residues are replaced by alanine of the respective Thai E2 mutants, YKATR/AAATA, Thai/TTTDK/AAADA, HKKW/AAAA, and RQGK/AQGA, are shown in light blue. (B) Nucleotide and amino acid sequences of the Fab fragment region of the CHE19 light chain and heavy chain. PCR primer sequences are shown in red (sense) and blue (antisense). The signal peptide sequence of each chain is highlighted in yellow. Variable regions of the light chain and heavy chain are highlighted in light blue and blue, respectively. (C-1) Deduced binding model no. 16 of CHE19 to the CHIKV spike protein. Ribbon drawings of the spike with the bound Fab fragment of CHE19 and whole model of CHE19. The E1 glycoprotein is shown in red, the E2 glycoprotein in green, and the CHE19 Fab fragment region or whole Fab fragment plus Fc structure is shown in blue for the heavy chain and light blue for the light chain.
