Coiled-coil interactions mediate serine integrase directionality
Serine integrases are bacteriophage enzymes that carry out site-specific integration and excision of their viral genomes. The integration reaction is highly directional; recombination between the phage attachment site attP and the host attachment site attB to form the hybrid sites attL and attR is essentially irreversible. In a recent model, extended coiled-coil (CC) domains in the integrase su...
متن کاملTRIM5α SPRY/coiled-coil interactions optimize avid retroviral capsid recognition
Restriction factors are important components of intrinsic cellular defense mechanisms against viral pathogens. TRIM5α is a restriction factor that intercepts the incoming capsid cores of retroviruses such as HIV and provides an effective species-specific barrier to retroviral infection. The TRIM5α SPRY domain directly binds the capsid with only very weak, millimolar-level affinity, and producti...
متن کاملComprehensive identification of human bZIP interactions with coiled-coil arrays.
In eukaryotes, the combinatorial association of sequence-specific DNA binding proteins is essential for transcription. We have used protein arrays to test 492 pairings of a nearly complete set of coiled-coil strands from human basic-region leucine zipper (bZIP) transcription factors. We find considerable partnering selectivity despite the bZIPs' homologous sequences. The interaction data are of...
متن کاملNew ELISA approach based on coiled-coil interactions.
The de novo designed heterodimeric E/K coiled-coil system has been previously demonstrated to be an excellent capture/dimerization system applicable to various needs in both biotechnology and pharmaceutical fields. Those include controlled protein dimerization, capture, purification and Western-blot detection. We here report the development of a new generation of ELISA test based on coiled-coil...
متن کاملData-Driven Prediction and Design of bZIP Coiled-Coil Interactions
Selective dimerization of the basic-region leucine-zipper (bZIP) transcription factors presents a vivid example of how a high degree of interaction specificity can be achieved within a family of structurally similar proteins. The coiled-coil motif that mediates homo- or hetero-dimerization of the bZIP proteins has been intensively studied, and a variety of methods have been proposed to predict ...
