Kurzbeschreibung (Abstract)
Chlorella viruses are a source of interesting membrane transport proteins. Here we examine a putative K(+) transporter encoded by virus FR483 and a few related chlorella viruses. The protein shares sequence and structural features with HAK/KUP/KT-like K(+) transporters from plants, bacteria and fungi. Yeast complementation assays and Rb(+) -uptake experiments show that the viral protein, termed HAKCV for High Affinity K(+) transporter Chlorella Virus, is functional with transport characteristics comparable to known K(+) transporters. Expression studies reveal that the protein is expressed as an early gene during viral replication and proteomics data indicate it is not packaged in the virion. The function of HAKCV is unclear but the data negate the hypothesis that the transporter substitutes for the role of viral-encoded K(+) channels during virus infection.
