General Information

EC Number General Information Comment Organism
3.5.4.B9 physiological function the enzyme causes mutational diversity by initiating mutations on regions of single-stranded DNA. The enzyme enters the cytoplasm of the targeted T cell and catalyzes C deaminations on reverse transcribed cDNA causing HIV-1 retroviral inactivation. Enzyme-initiated mutations boost human fitness and restricts HIV-1 replication in the absence of the viral infectivity factor. The enzyme is involved in hepatic metastasis of colorectal cancer Homo sapiens
