The overall fold was comprised of an N-terminal NAD(+) dinucleotide binding domain and a C-terminal UDP-sugar binding domain connected by a long alpha-helix, and the main-chain coordinates of the enzyme were similar to those of previously studied UDP-GDHs, including the enzymes from Burkholderia cepacia, Streptococcus pyogenes and Klebsiella pneumoniae. However, the sizes of several surface loops in P. islandicum UDP-GDH were much smaller than the corresponding loops in B. cepacia UDP-GDH but were comparable to those of the S. pyogenes and K. pneumoniae enzymes. Structural comparison revealed that the presence of extensive intersubunit hydrophobic interactions, as well as the formation of an intersubunit aromatic pair network, is likely to be the main factor contributing to the hyperthermostability of P. islandicum UDP-GDH.
