The points are drawn at a water molecule's estimated radius beyond the van der Waals radius, which is effectively similar to ‘rolling a ball’ along the surface. All points are checked against the surface of neighboring atoms to determine whether they are buried or a… franklin euro high yield fund

"WebAug 1, 2002 · The solvent accessible surface area (ASA) was computed using the program ACCESS (Hubbard, 1992), which is an implementation of the Lee and Richards (1971) algorithm. The ASA for each residue (and its side chain) were calculated without considering the non-proteinous constituents of the PDB files. " - Buried solvent-accessible surface area
