Interbacterial interactions can promote mutagenesis, and possibly adaptation, when intoxicated cells survive exposure to type VI secretion-delivered DNA deaminase toxins.
The first structures of Kaposi’s sarcoma-associated herpesvirus ORF68 and Epstein–Barr virus BFLF1, conserved and essential proteins required in herpesviruses, reveal new insights into viral genome packaging.
Patients with paucigranulocytic asthma may be more susceptible to severe influenza and could potentially be source of new, more virulent, influenza virus variants.
Distinct selective landscapes in mosquito and human cells shape dengue virus genetic diversity and highlight mechanisms of host adaptation in arboviruses.
A combined chemical genetics, proximity labeling, and ADP-ribose site mapping approach shows that PARP-7 mono-ADP-ribosylates immune-relevant proteins on cysteine amino acids.
PARP-7 is a mono(ADP-ribosyl) transferase that directs an extensive ADP-ribosylated proteome to control microtubule stability, and regulate ovarian cancer cell growth and motility.
The initiation of human genome replication requires the six-subunit origin recognition complex (ORC) and CDC6, with ORC playing additional roles during mitosis and in organization of the cell nucleus.
The first structure of a bacteriophage-encoded S-adenosyl methionine degrading enzyme was solved and demonstrated to catalyze a unimolecular lyase reaction occurring at the domain interface of a trimeric structure.
