Structure of creatine amidinohydrolase from Actinobacillus.
B.Padmanabhan, A.Paehler, M.Horikoshi.
The crystal structure of Actinobacillus creatine amidinohydrolase has been solved by molecular replacement. The amino-acid sequence has been derived from the crystal structure. Crystals belong to space group I222, with unit-cell parameters a = 111.26 (3), b = 113.62 (4), c = 191.65 (2) A, and contain two molecules in an asymmetric unit. The structure was refined to an R factor of 18.8% at 2.7 A resolution. The crystal structure contains a dimer of 402 residues and 118 water molecules. The protein structure is bilobal, consisting of a small N-terminal domain and a large C-terminal domain. The C-terminal domain has a pitta-bread fold, similar to that found in Pseudomonas putida creatinase, proline aminopeptidases and methionine aminopeptidase. Comparison with complex crystal structures of P. putida creatinase reveals that the enzyme activity of Actinobacillus creatinase might be similar to that of P. putida creatinase.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
