Methionine aminopeptidase (MetAP) catalyzes the removal of an amino-terminal methionine from a newly synthesized polypeptide. The enzyme was purified to homogeneity from Bacillus stearothermophilus (KCTC 1752) by a procedure that involves heat precipitation and four sequential chromatographs (including DEAESepharose ion exchange, hydroxylapatite, Ultrogel AcA 54 gel filtration, and Reactive red 120 dye affinity chromatography). The apparent molecular masses of the enzyme were 81,300 Da and 41…

Purification and Biochemical Characterization of Methionine Aminopeptidase (MetAP) from Mycobacterium smegmatis mc2155
The Methionine aminopeptidase (MetAP) catalyzes the removal of amino terminal methionine from newly synthesized polypeptide and is found to have a temperature and pH optimum of 50 °C and 8.5, respectively, and was found to be stable at50 °C with half-life more than 8 h.
A thermo‐stable lysine aminopeptidase from Pseudomonas aeruginosa: Isolation, purification, characterization, and sequence analysis
Pseudomonas aeruginosa NJ‐814, isolated from garden soil, produced an extracellular aminopeptidase that was purified using ammonium sulfate precipitation and ion exchange chromatography and it can be speculated that this enzyme is a Zn2+‐dependent enzyme and contains two zinc ions in its active site.
Molecular cloning, expression and characterization of three distinctive genes encoding methionine aminopeptidases in cyanobacterium Synechocystis sp. strain PCC6803
This is the first report of a prokaryote harboring multiple methionine aminopeptidases, and potential application of cyanobacterial MetAPs in the production of recombinant proteins used in medicine is proposed.
Extracellular methionine amino peptidase (MAP) production by Streptomyces gedanensis in solid-state fermentation
A bioprocess was developed for extracellular MAP production from Streptomyces gedanensis by solid-state fermentation and it resulted a maximum MAP production of 55.26 IU/g PUF after 120 h of fermentation.
Identification of antibacterial mechanism of l‐amino acid oxidase derived from Trichoderma harzianum ETS 323
The results indicate that the processes of bacterial interaction, membrane permeabilization and H2O2 production are involved in the mechanism responsible for the antibacterial activity of Th‐LAAO.
l‐leucine aminopeptidase production by filamentous Aspergillus fungi
Aims:  To screen various filamentous fungi belonging to Aspergillus spp. producing leucine and methionine aminopeptidases.


Purification and characterization of a methionine aminopeptidase from Saccharomyces cerevisiae.
The Purification and Characterization of Bacillus subtilis Tripeptidase (PepT)
A tripeptidase (PepT) was purified to homogeneity from Bacillus subtilis through four sequential chromatographies including DEAE-Sepharose ion exchange, hydroxylapatite, mono-Q FPLC ions exchange, and Superose-12 FPLC gel filtration, and the enzyme exists in a monomeric form.
Purification and partial characterization of a tripeptidase from Pediococcus pentosaceus K9.2
Strong inhibition of activity was caused by EDTA, 1,10-phenanthroline, dithiothreitol, and beta-mercaptoethanol, whereas phenylmethylsulfonyl fluoride and sulfur-reactive reagents had no effect on peptidase activity.

There are two cobalt-dependent MetAP families, presently composed of the prokaryote and yeast sequences, and by human MetAP, the yeast open reading frame, and the partial proKaryotic sequence (type II), on the other.
Methionine aminopeptidase from the hyperthermophilic Archaeon Pyrococcus furiosus: molecular cloning and overexpression in Escherichia coli of the gene, and characteristics of the enzyme.
Comparison of the amino acid sequence of P.f. furiosus MAP with those of other MAPs from Eukarya and Bacteria showed that the protein has a high degree of sequence homology in the stretches surrounding the five cobalt-binding residues fully preserved in all of MAPs determined so far, although it is distinct in lacking the N-terminal extension of about 90-150 residues universally found inMAPs fromEukarya.
The biochemical and molecular characterization of recombinant Bacillus subtilis tripeptidase (PepT) as a zinc-dependent metalloenzyme.
Data suggest that the B. subtilis PepT is likely to be a Zn 2+-dependent metalloenzyme and that the N-terminal region of the PepT stabilizes Zn2+-binding.
Crystal structure of methionine aminopeptidase from hyperthermophile, Pyrococcus furiosus.
Analysis of the PfMAP structure in comparison with EcMAP and other mesophile proteins reveals several factors which may contribute to the hyperthermostability of PfMAP: a significantly high number of hydrogen bonds and ion-pairs between side-chains of oppositely charged residues involved in the stabilization of helices.
Escherichia coli methionine aminopeptidase: implications of crystallographic analyses of the native, mutant, and inhibited enzymes for the mechanism of catalysis.
The structure of the His79Ala apoenzyme and the comparison of its electronic absorption spectra with other variants suggest that the loss in activity is not due to a conformational change or a defective metal center, and inhibitors analogous to that reported here may be useful in preventing angiogenesis in cancer and in the treatment of microbial and fungal infections.
