Figure 5.

Alignment of deduced amino acid sequences of EAS from different genotypes of N. attenuata (EASutah [AF542544], EAS12 [AF484123], EAS34 [AF484124], and EAS37 [AF484124]) and N. tabacum (5EAS). Amino acid differences are indicated by black shading. The gene consists of two domains: domain 1 (enclosed in box with a dotted line), which bisects domain 2 into two parts (both enclosed in boxes with a solid lines). Two conserved Mg²⁺-binding sites located in C-terminal portion of domain 2 are indicated by gray shading.
