TABLE 2 : A selection of amino acid positions in the 2930 PETase homologues from the LED. Amino acid residues that occurred in less than 50% of the sequences are listed in brackets for comparison with their previous mentions in literature. Amino acid substitutions “in LCC” refer to the position numbers used in 40. Some positions only occurred in a small subset of all PETase homologues and are thus indicated as gap symbols (-). Percentages indicate values rounded to integers. Sixteen positions and their corresponding amino acid symbols marked in red indicate the suggested PETase sequence motif, whereas the ones marked in green indicate additional positions that were used to select the sequences mentioned in the main text.
