This natural phenomenon is often referred to as the "Firefall", a name that pays homage to the manmade Firefall that once took place in Yosemite. This waterfall descends in two streams side by side, the eastern one being the larger
Sequence feature variant type a feature, the larger its number of variant types. For a given protein, once its amino acid sequence is determined, its sequence feature variant type is determined. SFVTs can be used to study the protein functions across many related species. Such studies have been carried out on several human pathogens. SFVTs are also available on Influenza Research Database for flu proteins and on Virus Pathogen Database and Analysis Resource for Dengue virus. Sequence feature variant type The Sequence Feature Variant Type (SFVT) refers to the defined sequence variation (mutation) of a given sequence feature in a protein. Consider a protein,
