Abstract
Aminopeptidase P (APPro, E.C 3.4.11.9) cleaves N-terminal amino acids from peptides and proteins where the penultimate residue is proline. This metal-ion-dependent enzyme shares a similar fold, catalytic mechanism, and substrate specificity with methionine aminopeptidase and prolidase. It adopts a canonical pita bread fold that serves as a structural basis for the metal-dependent catalysis and assembles as a tetramer in crystals. Similar to other metalloaminopeptidase, APPro requires metal ions for its maximal enzymatic activity, with manganese being the most preferred cation. Microbial aminopeptidase possesses unique characteristics compared with aminopeptidase from other sources, making it a great industrial enzyme for various applications. This review provides a summary of recent progress in the study of the structure and function of aminopeptidase P and describes its various applications in different industries as well as its significance in the environment.

Abstract
A proteome reference map of Neisseria gonorrhoeae was successfully established using two-dimensional gel electrophoresis in conjunction with matrix-assisted laser desorption ionization-time of flight mass spectrometry. This map was further applied to compare protein expression profiles of high-level spectinomycin-resistant (clinical isolate) and -susceptible (reference strain) N. gonorrhoeae following treatment with subminimal inhibitory concentrations (subMICs) of spectinomycin. Approximately 200 protein spots were visualized by Coomassie brilliant blue G-250 staining and 66 spots representing 58 unique proteins were subsequently identified. Most of the identified proteins were analysed as cytoplasmic proteins and belonged to the class of energy metabolism. Comparative proteomic analysis of whole protein expression of susceptible and resistant gonococci showed up to 96% similarity while eight proteins were found to be differentially expressed in the resistant strain. In the presence of subMICs of spectinomycin, it was found that 50S ribosomal protein L7/L12, an essential component for ribosomal translocation, was upregulated in both strains, ranging from 1.5- to 3.5-fold, suggesting compensatory mechanisms of N. gonorrhoeae in response to antibiotic that inhibits protein synthesis. Moreover, the differential expression of proteins involved in energy metabolism, amino acid biosynthesis, and the cell envelope was noticeably detected, indicating significant cellular responses and adaptation against antibiotic stress. Such knowledge provides valuable data, not only fundamental proteomic data, but also knowledge of the mode of action of antibiotic and secondary target proteins implicated in adaptation and compensatory mechanisms.

Production, active staining and gas chromatography assay analysis of recombinant aminopeptidase P from Lactococcus lactis ssp. lactis DSM 20481. AMB Express 2012; 2:39.

Abstract
The aminopeptidase P (PepP, EC 3.4.11.9) gene from Lactococcus lactis ssp. lactis DSM 20481 was cloned, sequenced and expressed recombinantly in E. coli BL21 (DE3) for the first time. PepP is involved in the hydrolysis of proline-rich proteins and, thus, is important for the debittering of protein hydrolysates. For accurate determination of PepP activity, a novel gas chromatographic assay was established. The release of L-leucine during the hydrolysis of L-leucine-L-proline-L-proline (LPP) was examined for determination of PepP activity. Sufficient recombinant PepP production was achieved via bioreactor cultivation at 16 °C, resulting in PepP activity of 90 μkatLPP Lculture-1. After automated chromatographic purification by His-tag affinity chromatography followed by desalting, PepP activity of 73.8 μkatLPP Lculture-1 was achieved. This was approximately 700-fold higher compared to the purified native PepP produced by Lactococcus lactis ssp. lactis NCDO 763 as described in literature. The molecular weight of PepP was estimated to be ~ 40 kDa via native-PAGE together with a newly developed activity staining method and by SDS-PAGE. Furthermore, the kinetic parameters Km and Vmax were determined for PepP using three different tripeptide substrates. The purified enzyme showed a pH optimum between 7.0 and 7.5, was most active between 50°C and 60°C and exhibited reasonable stability at 0°C, 20°C and 37°C over 15 days. PepP activity could be increased 6-fold using 8.92 mM MnCl2 and was inhibited by 1,10-phenanthroline and EDTA.

Abstract
Genomic analysis of a hyperthermophilic archaeon, Thermococcus sp. strain NA1, revealed the presence of a 1,068-bp open reading frame encoding a protein consisting of 356 amino acids with a calculated molecular mass of 39,714 Da (GenBank accession no. DQ144132). Sequence analysis showed that it was similar to the putative aminopeptidase P (APP) of Thermococcus kodakaraensis KOD1. Amino acid residues important for catalytic activity and the metal binding ligands conserved in bacterial, nematode, insect, and mammalian APPs were also conserved in the Thermococcus sp. strain NA1 APP. The archaeal APP, designated TNA1_APP (Thermococcus sp. strain NA1 APP), was cloned and expressed in Escherichia coli. The recombinant enzyme hydrolyzed the amino-terminal Xaa-Pro bond of Lys(Nepsilon-Abz)-Pro-Pro-pNA and the dipeptide Met-Pro (Km, 0.96 mM), revealing its functional identity. Further enzyme characterization showed the enzyme to be a Co2+-, Mn2+-, or Zn2+-dependent metallopeptidase. Optimal APP activity with Met-Pro as the substrate occurred at pH 5 and a temperature of 100 degrees C. The APP was thermostable, with a half-life of >100 min at 80 degrees C. This study represents the first characterization of a hyperthermophilic archaeon APP.

Abstract
A nested case-control study of low birth weight and preterm delivery was performed with singleton women. Immunoglobulin A (IgA) against the Gardnerella vaginalis hemolysin (anti-Gvh IgA) and sialidase and prolidase activities were determined in vaginal fluid at 17 weeks of gestation. Sialidase positivity and bacterial vaginosis with high prolidase activity were associated with 2- and 11-fold increased risks for low birth weight, respectively. No woman with bacterial vaginosis plus a strong anti-Gvh IgA response had an adverse outcome.

Abstract
Streptococcus gordonii is a primary etiological agent in the development of subacute bacterial endocarditis (SBE), producing thrombus formation and tissue damage on the surfaces of heart valves. This is ironic, considering its normal role as a benign inhabitant of the oral microflora. However, strain FSS2 of S. gordonii has been found to produce several extracellular aminopeptidase- and fibrinogen-degrading activities during growth in a pH-controlled batch culture. In this report, we describe the purification, characterization, and partial cloning of a predicted serine class arginine aminopeptidase (RAP) with some cysteine class characteristics. Isolation of this enzyme by anion-exchange, gel filtration, and isoelectric focusing chromatography yielded a protein monomer of approximately 70 kDa, as shown by matrix-assisted laser desorption ionization, gel filtration, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis under denaturing conditions. Nested-PCR cloning enabled the isolation of a 324-bp-long DNA fragment encoding the 108-amino-acid N terminus of RAP. Culture activity profiles and N-terminal sequence analysis indicated the export of this protein from the cell surface. Homology was found with a putative dipeptidase from Streptococcus pyogenes and nonspecific dipeptidases from Lactobacillus helveticus and Lactococcus lactis. We believe that RAP may serve as a critical factor for arginine acquisition during nutrient stress in vivo and also in the proteolysis of host proteins and peptides during SBE pathology.

Abstract
An aminopeptidase P (E.C. 3.4.11.9) that cleaves the Arg-1-Pro-2 bond of bradykinin has been isolated for the first time from Lactococcus lactis. The peptidase was purified to homogeneity in a 3-step procedure and characterized. It is a monomeric metalloenzyme with a 43 kDa molecular mass, activated by Mn2+ and inhibited by DTT. It differs from the majority of aminopeptidases P already described by displaying a specificity for X-Pro-Pro N-terminal and probably an extended binding site that could accommodate amino acid residues beyond the P'2 position of the substrate.

Abstract
Proline iminopeptidase (Pip) is a hydrolase elaborated by virtually all strains of Neisseria gonorrhoeae that selectively removes N-terminal proline residues from peptides. Escherichia coli clones expressing the gonococcal gene coding for Pip were identified in a genomic cosmid library using a synthetic colorimetric substrate. Nucleotide sequence determination and analyses of polypeptides detected by coupled in vitro transcription/translation reactions revealed that Pip is a 311-amino-acid polypeptide with a M(r) of 35 kDa and a pI of 5.4. Southern hybridization showed that the pip gene is present in a single copy on the chromosome of N. gonorrhoeae strain MS11 which maps immediately upstream of the previously identified opaA locus. The transcriptional start site of pip in E. coli, determined by primer extension analysis, was characteristic of an NtrA or sigma-54-dependent promotor. Complementation of an E. coli mutant deficient in both proline biosynthesis and dipeptide uptake confirmed that Pip is capable of releasing biologically active proline from peptides. Pip expression was found to be non-essential for in vitro growth of N. gonorrhoeae, based on the viability of a Pip- gonococcal mutant.

Abstract
Proline iminopeptidase was extracted from the cells of a strain of Propionibacterium acnes and purified. The molecular weight was estimated to be about 120,000 by SDS-polyacrylamide gel electrophoresis. The enzyme showed the highest activity at 50 degrees C-55 degrees C and its optimum pH was found at 7.5-8.0. The enzyme activity was inhibited by p-chloromercuribenzoate, indicating that this peptidase is a SH-enzyme. Especially prolyl-glycyl-glycine but also prolyl-proline bonds were hydrolyzed by this enzyme, glycyl-proline was not split.

Abstract
A specific procedure has been developed for the detection of the first two enzymes involved in the arginine dihydrolase system and the detection of the decarboxylases of arginine, glutamic acid, histidine, lysine, ornithine, phenylalanine, tryptophan, and tyrosine. A loopful of growth of each organism from dihydrolase-decarboxylase induction agar medium (or broth) was washed and incubated separately with 0.2-ml samples of three test media supplemented with different amino acids. Each spent test medium was dansylated, and the dansyl derivatives were separated by two-dimensional thin-layer chromatography on polyamide sheets. The end products (citrulline, ornithine, gamma-amino-n-butyric acid, and amines) produced during incubation were estimated by comparing the fluorescent intensities of end products from the spent test media and of the corresponding parent amino acids from test medium controls after thin-layer chromatography. The method is reproducible, requiring incubation of an organism in three test media for 1 h for simultaneous detection of the first two enzymes involved in the arginine dihydrolase system and of eight amino acid decarboxylases. This method has been successfully applied to gram-positive and gram-negative microorganisms and also to Mycoplasmatales. It could simplify and improve the accuracy of the corresponding biochemical tests performed in clinical laboratories for the identification and differentiation of microorganisms, and it may prove particularly useful for the differentiation of species of Pseudomonas and Mycoplasma.

Abstract
The 125I-labeled tryptic peptides of the outer membrane protein I of 33 previously characterized serological reference strains of Neisseria gonorrhoeae were investigated by peptide maps in relation to their coagglutination W serogroup. Serogroup WI strains tended to have lower-molecular-weight protein I molecules than did WII strains, and WIII strains had the highest-molecular-weight protein I molecules, although the serogroup could not be predicted from the molecular weights of the protein I molecules for a given strain. All 13 strains belonging to serogroup WI were found to have 11 peptides in common, as judged by their migration with respect to one another and to the internal marker valine in the peptide maps. Common peptides isolated from a given strain were found to comigrate with the corresponding common peptides from other strains in the same serogroup under various electrophoretic conditions. The 20 strains belonging to serogroups WII and WIII were all found to have 10 common peptides by the same criteria. When common peptides from serogroup WI were compared with the common peptides of serogroups WII and WIII, only three of these peptides appeared to be similar. Thus, two different outer membrane protein I molecules seem to exist which are mutually exclusive. Protein IA molecules contain the antigens recognized as serogroup WI, and protein IB molecules contain the antigens that characterize serogroups WII and WIII.

Abstract
Neisseria gonorrhoeae contains several hydrolases which may be responsible for gonococcal cell lysis. One of these enzymes, an endo-beta-N-acetyl-D-glucosaminidase, has been extracted from supernatants of sonicated gonococci and partially purified by ammonium sulfate precipitation and affinity and ion-exchange chromatography. This enzyme has a different specificity than egg white lysozyme and cleaves the beta 1 leads to 4 glycosidic linkage between N-acetylglucosamine and N-acetylmuramic acid in gonococcal peptidoglycan.
