This shows the full-length sequence of the enzyme. The region of the functional domain is highlighted in black letters, while the residual residues are shown in grey. The Superfamily domain, when present, is shown using underlining. In many cases the functional domain is the full-length sequence.
Conserved catalytic residues (as determined by automated alignment to family, subgroup, or superfamily HMMs) are shown with teal highlighting . Conserved catalytic residues which do not matched the Conserved Alignment Residue are shown with maroon highlighting . Information regarding their function can be found in the Conserved Residues section below.
