(A) The central channel in the PfFNT-MMV007839 protomer viewed from the parasite's membrane plane. The channel, calculated by HOLE (Smart et al., 1996), is indicated by blue dots. There is one constriction site (colored red) formed in the central channel. Residues forming the constriction are in green sticks. Residues that line the rest of the channel are in cyan sticks. (B) Representative figure of the calculated diameters of a PfFNT-MMV007839 protomer.
