The percentage of proteins correctly predicted to fall into the globular or transmembrane class

523 globular and 158 TM proteins have been selected as given in the text. A TM region is defined as that part of the sequence for which a 15-residue segment is invariably predicted as a TM helix by the given number (1 to 4) of prediction methods. For each case the number and percentage of proteins predicted to have no (for globular proteins) or to have (for transmembrane proteins) TM region(s) is calculated. The 11 globular proteins that have TM region(s) by at least three methods are: 1bia, 1ciy, 1din, 1frp, 1lci, 1lcp, 1oxa, 1phg, 1ytb, 2adm, and 2pia; the only such protein by four methods is 1din. The sum of total numbers yields the percent probability of classifying any randomly selected protein correctly in terms of the class it belongs to.
