General description

Methionine aminopeptidase from Pyrococcus furiosus is a 32 kDa thermostable enzyme. It belongs to type 2a class of methionine aminopeptidase. Methionine aminopeptidase maintains protein homeostasis and coordinates posttranslational modification of proteins in eukaryotes.
X-ray crystallography of the structure of methionine aminopeptidase from Pyrococcus furiosus or PfMAP was performed at a resolution of 1.75A and showed that the protein consists of a catalytic domain containing two cobalt ions in the active site and a unique insertion domain which is specific to the prokaryotic form of the protein.

Application

Methionine Aminopeptidase from Pyrococcus furiosus has been used in a study to analyze the binding of Co(II)-specific inhibitors to the methionyl aminopeptidases from Escherichia coli and Pyrococcus furiosus. It has also been used in a study to examine the binding of a new class of pseudopeptide analog inhibitors.

Biochem/physiol Actions

Thermostable methionine aminopeptidase, which specifically liberates the N-terminal methioinine from proteins and peptides.

Unit Definition

One unit will hydrolyze 1 μmol of Met from Met-Pro-Ala-Ala-Gly in 1 minute at pH 7.5 at 37 °C.

Physical form

Solution containing 0.01% Tween® 20, 0.1 mM CoCl2, and 10 mM Tris-HCl, pH 7.5.

Methionine aminopeptidases (MetAPs) represent a unique class of protease that is capable of the hydrolytic removal of an N-terminal methionine residue from nascent polypeptide chains. MetAPs are physiologically important enzymes; hence, there is considerable interest in developing inhibitors that can
