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

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.
