CcoN subunit, aside from the suggested pathway entrance, which is at the Glu-49 in CcoP (corresponding to E-25 in the CcoP sequence). The pathway extends via a cluster of polar residues (Tyr-223, Ser-240, His-243, Tyr-317, and Thr-215, all conserved in from the O2 binding site (16). Open in a separate… Continue reading Supplementary Materials Supporting Information supp_108_43_17661__index. CcoN subunit, aside from the suggested
