  • PubMed Abstract: 
  • Klebsiella pneumoniae pullulanase (KPP) belongs to glycoside hydrolase family 13 subfamily 13 (GH13_13) and is the only enzyme that is reported to perform an induced-fit motion of the active-site loop (residues 706-710). Comparison of pullulanase structures indicated that only KPP has Leu680 present behind the loop, in contrast to the glycine found in other GH13_13 members ...

    Klebsiella pneumoniae pullulanase (KPP) belongs to glycoside hydrolase family 13 subfamily 13 (GH13_13) and is the only enzyme that is reported to perform an induced-fit motion of the active-site loop (residues 706-710). Comparison of pullulanase structures indicated that only KPP has Leu680 present behind the loop, in contrast to the glycine found in other GH13_13 members. Analysis of the structure and activity of recombinant pullulanase from K. pneumoniae ATCC 9621 (rKPP) and its mutant (rKPP-G680L) indicated that the side chain of residue 680 is important for the induced-fit motion of the loop 706-710 and alters the binding affinity of the substrate.
