Differences in sugar conformation affect how APOBEC3A and APOBEC3B enzymes recognize nucleic acids and catalyze C-to-U deamination. See our new work in ACS Chem. Biol. (pdf).
Congratulations to Katherine and our collaborators for their ACS Med. Chem. Lett. manuscript on APOBEC3A stability with mutations to the catalytic glutamic acid! [pdf]
