PSIMAP(Protein structural Interactome MAP) is a tool for constructing interactomes. It is a general protocol of mapping proteins and their family interactions.
PSIMAP algorithms
- FAC (Full Atom Contact)
- - caltulates all the atomic contacts among two or more protein structural domians. - Most accurate of the three.
- SAC (Sampled Atom Contact)
- - Sample every 3rd or 4th atom. - to reduce the time taken in constructing PSIMAP.
- BBC (Bounding Box Contact)
- - using a bounding box algorithm to dramatically reduce the time of computation. - Dafas and Schroeder et al., introduced a bounding box and convex hull alogrithm that can reduce the search space.
