Comparison of the FBP-BS and N-terminal extensions in C. apon LDH with representative allosteric and nonallosteric Apo LDHs. a) B. long LDH (allosteric), b) C. apon LDH (allosteric, this work), and c) H. sapi LDH (nonallosteric) as Apo proteins. Structures are represented along the P-axis for observation of the FBP-BSs (purple wheel in B. long LDH and C. apon LDH) and the N-terminal extensions (in C. apon LDH and H. sapi LDH). Monomers are colored as on Fig. 4. With the exception of amino acid of the N-terminal extension (blue and green), the positions are normalized with respect to LDH nomenclature (Eventoff et al. 1977).
