This is version 1.20 of the Surface Entropy Reduction prediction (SERp) server from January 2007. This exploratory tool aims to aid identification of sites that are most suitable for mutation designed to enhance crystallizability by a Surface Entropy Reduction approach.

This server is no longer supported and no longer requires authentication.
Job submissions are not available at the moment.

The meta search attempts to detect other potential crystallization failure modes and identify sequence regions that may be important for function.

List homologous structures (PDBs) and performs a DSSP analysis for solvent accessibility.

BLOCKS » BLOCKS website
Blocks are multiply-aligned, ungapped segments corresponding to the most highly conserved regions of proteins. This search identifies highly conserved motifs such as metal binding sites; addition of the corresponding metal may be required for crystallization.
