Figure 1

A comparison of the length and metal binding regions of amino acid sequences for Hst 5, Hst 5ΔMB, and P113. Three metal binding motifs are labeled—ATCUN (Cu2+, orange), HExxH (Zn2+, blue), and (H)AKRHH (Zn2+, light blue). P113 is truncated to amino acids 4-15 of Hst 5. The ATCUN (AA 1-3) and HExxH (AA 15-19) motifs of Hst 5ΔMB are mutated to glutamines.
