Abstract The APOBEC3 (A3) family of cytidine deaminases plays a vital role for innate defense against retroviruses. Lentiviruses such as HIV-1 evolved the Vif protein that triggers A3 protein degradation. There are seven A3 proteins, A3A-A3H, found in humans. All A3 proteins can deaminate cytidines to uridines in single-stranded DNA (ssDNA), generated during viral reverse transcription. A3 proteins have either one or two cytidine deaminase domains (CD). The CDs coordinate a zinc ion, and their…

Structural determinants of human APOBEC3A enzymatic and nucleic acid binding properties

A3A’s potential to mutate genomic DNA during transient strand separation is demonstrated and this process could be counteracted by ssDNA binding proteins.

Structural basis of chimpanzee APOBEC3H dimerization stabilized by double-stranded RNA

This work reveals the 2.20-Å crystal structure of the chimpanzee A3H (cpzA3H) dimer bound to a short double-stranded RNA (dsRNA), which appears to be similar to two recently reported structures of pig-tailed macaque A 3H and human A3h.

Influence of the DNA sequence/length and pH on deaminase activity, as well as the roles of the amino acid residues around the catalytic center of APOBEC3F.

It was shown that the deaminase activity of A3F-CTD is affected by the nucleic acid residues adjacent to the target sequence, TC, and that TTCA/G are the most preferred sequences, and it could be regulated through phosphorylation of a putative site, S216.

A3s can be considered as a potent defensive tool of the innate immunity network against retroviral spread and infection and contributes on the better understanding of the molecular function of the A3 enzymes.

It is hypothesized that A4 may have a natural role in modulating host promoters or endogenous LTR promoters, regardless of whether they were viral or mammalian.

Interactions between APOBEC3 and murine retroviruses: Mechanisms of restriction and drug resistance

It is shown that endogenous APOBEC3 protein is efficiently packaged into viral cores, and this protein maintains catalytic activity against artificial substrates, and can be targeted through virion-packaged or cell-associated protein.



RNA-Dependent Oligomerization of APOBEC3G Is Required for Restriction of HIV-1

It is proposed that occupation of the positively charged pocket by RNA promotes A3G oligomerization, packaging into virions and antiviral function.

The structure of the APOBEC3G catalytic domain will help to understand functions of other family members and interactions that occur with pathogenic proteins such as HIV-1 Vif and Escherichia coli-based activity assays.

An extended structure of the APOBEC3G catalytic domain suggests a unique holoenzyme model.

Model structure of APOBEC3C reveals a binding pocket modulating ribonucleic acid interaction required for encapsidation

This study modeled and probed the structure of APOBEC3C (A3C), a single-domain A3 with strong antilentiviral activity and found that A3C activity requires protein dimerization for antiviral activity against SIV.

NMR structure of human restriction factor APOBEC3A reveals substrate binding and enzyme specificity

The NMR solution structure of A3A is reported and it is shown that the critical interface for interaction with ssDNA substrates includes residues extending beyond the catalytic center, involving key determinants immediately 5′ of the reactive C.

Biochemical Activities of Highly Purified, Catalytically Active Human APOBEC3G: Correlation with Antiviral Effect

It is demonstrated that APO3G deaminates cytosines in single-stranded DNA (ssDNA) only, whereas it binds efficiently to ssDNA and ssRNA, about half as well to a DNA/RNA hybrid, and poorly to double-stranding DNA and RNA.

Structural Model for Deoxycytidine Deamination Mechanisms of the HIV-1 Inactivation Enzyme APOBEC3G*♦

A structure-based model is proposed to explain the scanning and catalytic behavior of Apo3G, a single-stranded DNA-dependent deoxycytidine deaminase, which, in the absence of the human immunodeficiency virus, is encapsulated into HIV virions.

SummaryThe AID/APOBECs, a group of cytidine deaminases, represent a somewhat unusual protein family that can insert mutations in DNA and RNA as a result of their ability to deaminate cytidine to

The APOBEC3C crystal structure and the interface for HIV-1 Vif binding

A high-resolution crystal structure of APOBEC3C is reported and the role of a shallow cavity composed of hydrophobic or negatively charged residues between the α2 and α3 helices is revealed, which could provide insight into Vif-A3 interactions and could lead to the development of new pharmacologic anti–HIV-1 compounds.
