TipαN 34 -I adopts a similar dimeric organization mode with that of TipαN 25 (C), however the dimeric β-sheets are oriented away from the dimeric interface by 10° (D) a... d some residue contacts involved in dimer interactions are instabilized (E) in TipαN 34 -I. TipαN 25 (3VNC), TipαN 28 (3GIO), TipαN 28 (3GUQ), TipαN 34 -I (2WCQ), and TipαN 34 -II (2WCR) are coloured in red, blue, yellow, cyan and deepsalmon, respectively.
Protein Data Bank Accession Number Coordinates and structure factors for the structure of TipαN 25 have been deposited to Protein Data Bank with the accession code 3VNC.
