Implication of a central cysteine residue and the HHCC domain of Moloney murine leukemia virus integrase protein in functional multimerization.

چکیده
Moloney murine leukemia virus (M-MuLV) IN-IN protein interactions important for catalysis of strand transfer and unimolecular and bimolecular disintegration reactions were investigated by using a panel of chemically modified M-MuLV IN proteins. Functional complementation of an HHCC-deleted protein (Ndelta105) by an independent HHCC domain (Cdelta232) was severely compromised by NEM modification of either subunit. Productive Ndelta105 IN-DNA interactions with a disintegration substrate lacking a long terminal repeat 5'-single-stranded tail also required complementation by a functional HHCC domain. Virus encoding the C209A M-MuLV IN mutation exhibited delayed virion production and replication kinetics.

Functional interactions of the HHCC domain of moloney murine leukemia virus integrase revealed by nonoverlapping complementation and zinc-dependent dimerization.
The retroviral integrase (IN) is required for the integration of viral DNA into the host genome. The N terminus of IN contains an HHCC zinc finger-like motif, which is conserved among all retroviruses. To study the function of the HHCC domain of Moloney murine leukemia virus IN, the first N-terminal 105 residues were expressed independently. This HHCC domain protein is found to complement a com...
متن کاملAssembly and catalysis of concerted two-end integration events by Moloney murine leukemia virus integrase.
Retroviral integration results in the stable and coordinated insertion of the two termini of the linear viral DNA into the host genome. An in vitro concerted two-end integration reaction catalyzed by the Moloney murine leukemia virus (M-MuLV) integrase (IN) was used to investigate the binding and coordination of the two viral DNA ends. Comparison of the two-end integration and strand transfer a...
متن کاملRous sarcoma virus integrase protein: mapping functions for catalysis and substrate binding.
Rous sarcoma virus (RSV), like all retroviruses, encodes an integrase protein that is responsible for covalently joining the reverse-transcribed viral DNA to host DNA. We have probed the organization of functions within RSV integrase by constructing mutant derivatives and assaying their activities in vitro. We find that deletion derivatives lacking the amino-terminal 53 amino acids, which conta...
متن کاملFunctional analysis of N-terminal residues of ty1 integrase.
The Ty1 retrotransposon of Saccharomyces cerevisiae is comprised of structural and enzymatic proteins that are functionally similar to those of retroviruses. Despite overall sequence divergence, certain motifs are highly conserved. We have examined the Ty1 integrase (IN) zinc binding domain by mutating the definitive histidine and cysteine residues and thirteen residues in the intervening (X(32...
متن کاملAnalysis of the contribution of reverse transcriptase and integrase proteins to retroviral RNA dimer conformation.
All retroviruses contain two copies of genomic RNA that are linked noncovalently. The dimeric RNA of human immunodeficiency virus type 1 (HIV-1) undergoes rearrangement during virion maturation, whereby the dimeric RNA genome assumes a more stable conformation. Previously, we have shown that the packaging of the HIV-1 polymerase (Pol) proteins reverse transcriptase (RT) and integrase (IN) is es...
