Partial Atomic Model of the Tailed Lactococcal Phage TP901-1 as Predicted by AlphaFold2: Revelations and Limitations

Bacteria are engaged in a constant battle against preying viruses, called bacteriophages (or phages).These remarkable nano-machines pack and store their genomes in a capsid and inject it into the cytoplasm of their bacterial prey following specific adhesion to the host cell surface.Tailed phages possessing dsDNA genomes are the most abundant phages

On a Class of Graphs with Large Total Domination Number

fr6122 Let $gamma(G)$ and $gamma_t(G)$ denote the domination number and the total domination number, respectively, of a graph $G$ with no isolated vertices.It is well-known that $gamma_t(G) leq 2gamma(G)$.We provide a characterization of a large family of graphs (including chordal graphs) satisfying $gamma_t(G)= 2gamma(G)$, strictly generalizing th
