An algorithm is presented for calculating the solvent accessible surface area of proteins using a threedimensional grid. Since it requires only calculations based on single atomic positions, the algorithm is easy to be vectorized. It has been implemented on STlOO and may also be implemented on super

โฆ Synopsis
An improved version of the "marching-cube" method' is proposed for molecular surface triangulation. This new algorithm involves fewer and simpler basic building blocks and avoids the artificial gaps of the original one. Moreover, to make it applicable to the boundary element method, the procedures for the protein cavity identification and triangle reduction are also presented. The triangulation procedure was tested by incorporating it into the boundary element method (BEM) to estimate the pK, values of subtilisin BPN' and bovine trypsin inhibitor (BPTI).
