Figure 1
Crystal structure of the class 1 type II L-asparaginase from E. coli (PDB entry 3eca). (a) Two intimate dimers (A–B, green–pink; C–D, blue–orange) make up the EcAII homotetramer. The four active sites are marked by yellow circles with L-Asp molecules in CPK representation. (b) The intimate dimer (chain A, green; chain B, pink) of EcAII possesses two active sites [marked as in (a)]. (c) Detailed view of the active site of protomer A with a pattern of hydrogen bonds (red dashed lines) stabilizing the product molecule (L-Asp, yellow). |
