Schematic diagram of the Ski2 RNA helicase family in G. lamblia. Each Sec63 domain is represented in pink, the DsHCT domain in brown, and the HhH1 domain in violet, all inside the C-terminal region of each ORF. Red lines within the N- or C-terminal extensions represent the region amplified in the qPCR for each putative helicase. The two overlap repeats of ~ 650 amino acids are indicated in blue under the ORF 87022. The representation is to scale. Inset: sequence LOGO view of the consensus amino acids. The height of each amino acid represents the degree of conservation. Colors mark properties of the amino acids, as follows: green (polar), blue (basic), red (acidic) and black (hydrophobic).
