Ramachandran plots of the catalytic base loop
residues Asp38(Glu),
Pro39(Gly), Val40(Gly), Gly41, and Ser42(Gly) obtained from MD trajectories
by calculating the probability distribution function averaged over
all data sets. The x-axis corresponds to angle φ
(degrees), and the y-axis corresponds to angle ψ
(degrees). Each row corresponds to the specified mutant, and each
column corresponds to the specified residue in the catalytic base
loop.
