Correlation of calculated rates of ligand entry, kNO, and kO2 in CerHb. A, kentry versus kNO; B, kO2 versus kNO for Val-7(B6)Ala, -Phe, and -Trp; Thr-48(E11)Val; Ala-55(E18)Val, -Leu, -Phe, and -Trp; Leu-86(G12)Ala, -Phe, and -Trp; Gln-44(E7)Trp; and Val-7(B6)Phe/Ala-55(E18)Phe/Leu-84(G12)Phe CerHb mutants (supplemental Table S2). C, kentry versus kO2, open circles, all single mutants are located in and along the apolar tunnel (supplemental Table S1); closed circles, multiple mutants are located in the apolar tunnel (supplemental Table S4).
