Comparative quantitative analysis of amino acid patterns at EXXR and CXG (FXXGXRXCXG) motifs in 54 P450 families.

<p>The percentage predominance of amino acids at particular positions is calculated considering the total number of amino acids as 100%. Amino acids or patterns of amino acids contributing more than 50% at the specific position are shown in the table. Amino acids conserved (100%) at the specific position(s) are represented by their symbol. The numerical values in the table are percentage values.
