Stimsons Pythons T+ Albino (Anatersia Stimsoni) Also known as "Albino Blonde" this fantastic looking colour variation of the Stimson's Python is a relatively new one to Australia that has now become available for sale. "t+" means "tyrosinase-positive" Tyrosinase is an enzyme that acts on tyrosine, an amino acid that is the basic building block of melanin and a suite of other dark pigments that are called melanin-related pigments. A tyrosinase-positive albino has functional tyrosinase and it is able to complete the first and second steps of the multi-step process of black melanin synthesis. Some other enzyme along the synthesis is missing. Tyrosinase-positive albinos do not make black melanin, but they do make other melanin-related pigments. Melanin-related pigments are mostly dark colours and they include a purple-gray, dark gray, gray brown, a dark yellowish brown, and several shades of brownish-red, dark red or medium red.
