Analysis of UL and LL in CcEstA, R61 DD-peptidase (3PTE), and PaPBP (2QMI).
(A) Catalytic residues are colored in cyan. The residues of UL are in yellow and those of LL are in green. (B,C) Molecular surface representation of UL and LL in ribbon diagram. Front view (B) and top view (C) are shown. Note that the orientation of UL and LL in CcEstA is different from those of R61 DD-peptidase (3PTE) and PaPBP (2QMI).
