Potential hotspots affecting substrate specificity were selected through homology modeling, evolutionary conservation analyses, and substrate-docking modeling of Xltr1p. Variants carrying mutations at these hotspots were subsequently obtained via in silico screening. Replacement of Leu174 or Asn297 in Xltr1p with alanine resulted in loss of hexose transport activity, indicating that Leu174 and Asn297 play essential roles in hexose transport. The Y301W variant exhibited accelerated mannose transport, but lost galactose transport capacity, and mutation of Gln291 to alanine greatly accelerated mannose transport. These results suggest that amino acids located in transmembrane α-helix 7 (Asn297, Tyr301, and Gln291) play critical roles in substrate recognition by the hexose transporter Xltr1p.

Elucidating the host-factor/viral-protein interaction network will reveal new targets for developing novel antiviral therapies. Using proteomic analysis, we identified 255 cellular proteins that interact with the ASFV-encoded pE301R protein when transiently expressed in HEK293T cells. Gene ontology (GO) annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) database enrichment, and protein-protein interaction (PPI) network analyses revealed that pE301R-interacting host proteins are potentially involved in various biological processes, including protein translation and folding, response to stimulation, and mitochondrial transmembrane transport.

Carotenoids, low-molecular-weight pigments known for their antioxidative activity, are delivered to humans through oral intake. However, it remains unclear whether human intestinal bacteria biosynthesize carotenoids as part of the <em>in-situ</em> microbiota. In this study, we investigated carotenoid synthesis genes in various human gut and probiotic bacteria. As a result, novel candidates, the <em>crtM</em> and <em>crtN</em> genes, were identified in the carbon monoxide-utilizing gut anaerobe <em>Eubacterium limosum</em> and the lactic acid bacterium <em>Leuconostoc mesenteroides</em> subsp. <em>mesenteroides</em>.
