Enzyme-catalyzed DNA Cytidine Deamination in Human Biology

Over the past decade, we have learned that humans have ten DNA cytidine deaminases that catalyze a variety of physiological functions from triggering antibody gene diversification to providing innate immunity to a broad number of foreign DNA elements such as viruses and transposons. I will review the biology of these enzymes and discuss recent biochemical and structural advances that help us to better appreciate their integral cellular functions (1-4)
