Figure 2. Binding of the substrate peptide in the active site of Balc424.

Figure 2

(A) Figure shows the substrate peptide (QRATKM) binding in the active site of Balc424. Balc424 is shown in solid blue-colored surface. Substrate peptide is shown in sphere (CPK) model. Carbon, oxygen, nitrogen, sulfur and zinc atoms are shown in green, red, blue, yellow and magenta, respectively. (B). Superposed stick models of QRATKM and RRATKM are shown in green, and gray, respectively. Carbon atoms are shown in green (QRATKM) and gray (RRATKM). Balc424 is shown in semi-transparent surface (blue) representation with secondary elements at the active site pocket. Only a few substrate-binding residues are shown as markers. Pymol (DeLano, W.L. The PyMOL Molecular Graphics System (2002) on World Wide Web http://www.pymol.org) was used to prepare these figures.
