  • a The deduced properties of the gene products of orf1 to orf11 (as determined by diverse computer programs) are compared with the properties of phenol-induced proteins detected in two-dimensional gels.

  • b Numbers in parentheses refer to the numbers of the spots of corresponding proteins in a two-dimensional gel in Fig.2.

  • c Dir, direction of transcription. The range is of the nucleotides of the corresponding gene.

  • d Mol mass, molecular mass; pI, isoelectric point; Exp., experimentally determined (two-dimensional gels); aa, amino acids. The length is the number of amino acids of the corresponding translated gene product.

  • e Overall similarity and identity of the amino acid sequence to proteins in the databases are given. % Identity, the percentage of amino acids that are identical between the two proteins; % Similarity, the percentage of amino acids that are identical or conserved between the two proteins; E value, Expect value. The Expect value estimates the statistical significance of the match, specifying the number of matches, with a given score, that are expected in a search of a database of this size absolutely by chance.

  • f Given are references of similar proteins. Database accession numbers are in parentheses.
