Figure 1.

(A) Nucleotide sequence of the full-length HvCBT1 along with the amino acid sequence of the longest ORF. The RACE primers are shown in boldface type, the six putative transmembrane domains are underlined, the H5 domain is dashed underlined, the putative cyclic nucleotide binding domain is double underlined, and the CaM binding domain is dotted underlined. (B) Hydropathy plot of the deduced amino acid sequence of HvCBT1. The H5 region as well as the six transmembrane domains (S1–S6) are indicated. Negative values indicate hydrophobic regions.
