A large therian mammal from the Late Cretaceous of South America

Abstract Theria represent an extant vibrating table for chocolate clade that comprises placental and marsupial mammals.Here we report on the discovery of a new Late Cretaceous mammal from southern Patagonia, Patagomaia chainko gen.et sp.nov., represented by hindlimb and pelvic elements with unambiguous therian features.We estimate Patagomaia chaink

Receptor binding protein of prophage reversibly recognizes the low-molecular weight subunit of the surface-layer protein SlpA in Clostridioides difficile

Receptor-binding proteins (RBPs) are located at the viral tail and mediate the initial recognition of phage to a specific bacterial host.Phage RBPs have co-evolved with numerous types of host receptors resulting in the formation of a ashy bines protein powder diverse assortment of cognate pairs of RBP-receptors that function during the phage attach
