Fig. 4From: Evolutionary loss of melanogenesis in the tunicate Molgula occulta Tyrosinase family pseudogenization in Molgula occulta. The figure points out the presence of premature stop codons (red) and frameshift insertions (magenta) in genomic sequences of Tyrp.a (a) and Tyr (b). A reconstruction of the active site of the proteins has been obtained using the SMART Web site [58]. Certain Mooccu.Tyr alleles are characterized by the presence of transposable elements (yellow) inserted just upstream of the active site (b)Back to article page
