ABSTRACT We present an evaluation of our protein-protein docking approach using the ZDOCK and ZRANK algorithms, in combination with structural clustering and filtering, utilizing biological data in Rounds 6-11 of the CAPRI docking experiment. We achieved at least one prediction of acceptable accuracy for five of six targets submitted. In addition, two targets resulted in medium-accuracy predictions. In the new scoring portion of the CAPRI exercise, we were able to attain at least one acceptable prediction for the three targets submitted and achieved three medium-accuracy predictions for Target 26. Scoring was performed using ZRANK, a new algorithm for reranking initial-stage docking predictions using a weighted energy function and no structural refinement. Here we outline a practical and successful docking strategy, given limited prior biological knowledge of the complex to be predicted.

    ABSTRACT: Protein-protein interactions are essential to cellular and immune function, and in many cases, due to absence of an experimentally determined structure of the complex, these interactions must be modeled to obtain an understanding of their molecular basis. We present a user-friendly protein docking server, based on the rigid-body docking programs ZDOCK and M-ZDOCK, to predict structures of protein-protein complexes and symmetric multimers. With a goal of providing an accessible and intuitive interface, we provide options for users to guide the scoring and selection of output models, in addition to dynamic visualization of input structures and output docking models. This server enables the research community to easily and quickly produce structural models of protein-protein complexes and symmetric multimers for their own analysis. The ZDOCK server is freely available to all academic and non-profit users at: No registration is required. or

    ABSTRACT: Protein–protein docking is attracting increasing attention in drug discovery research targeting protein–protein interactions, owing to its potential in predicting protein–protein interactions and ‘hot spot’ residues at the protein–protein interface. Given the relative lack of information about binding sites and the fact that proteins are generally larger than ligand, the search algorithms and evaluation methods for protein–protein docking differ somewhat from those for protein–ligand docking and, hence, require different research strategies. Here, I review the basic concepts, principles and advances of current search strategies and evaluation methods for protein–protein docking. I also discuss the current challenges and limitations, as well as future directions, of established approaches.

    ABSTRACT: Abstract Mycobacterium tuberculosis (Mtb) is an intracellular human parasite that causes tuberculosis (TB). The parasite is capable of surviving under stress conditions. The gene expression in Mtb is regulated by sigma factor family of proteins. The SigF protein belongs to the sigma factor family, expressed during stationary and growth phase, 14 genes are directly regulated by SigF and has a role in the expression of the principal sigma factor SigB as well. The interacting partner Usfx, the anti SigF protein, controls the regulation of SigF. The structures of SigF and Usfx were evaluated using comparative modelling techniques and validated. The active sites of the two proteins were identified. The protein-protein interaction studies between SigF and Usfx reveal His53, Phe226 and Asp227 residues of SigF protein to be involved in binding with Arg108, Arg130 and Glu140 amino acids of Usfx. The present study focuses on identification of important residues involved in binding of SigF protein with Usfx, which are essential in the inhibition of transcription initiation and survival of Mtb.
