Formed from pig pepsinogen by cleavage of one peptide bond. The enzyme is a single polypeptide chain and is inhibited by methyl 2-diaazoacetamidohexanoate. It cleaves peptides preferentially at the carbonyl linkages of phenylalanine or leucine and acts as the principal digestive enzyme of gastric juice.
Proenzymes secreted by chief cells, mucous neck cells, and pyloric gland cells, which are converted into pepsin in the presence of gastric acid or pepsin itself. (Dorland, 28th ed) In humans there are 2 related pepsinogen systems: PEPSINOGEN A (formerly pepsinogen I or pepsinogen) and PEPSINOGEN C (formerly pepsinogen II or progastricsin). Pepsinogen B is the name of a pepsinogen from pigs.
A family of intracellular CYSTEINE ENDOPEPTIDASES that play a role in regulating INFLAMMATION and APOPTOSIS. They specifically cleave peptides at a CYSTEINE amino acid that follows an ASPARTIC ACID residue. Caspases are activated by proteolytic cleavage of a precursor form to yield large and small subunits that form the enzyme. Since the cleavage site within precursors matches the specificity of caspases, sequential activation of precursors by activated caspases can occur.
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
A long pro-domain caspase that contains a death effector domain in its pro-domain region. Caspase 8 plays a role in APOPTOSIS by cleaving and activating EFFECTOR CASPASES. Activation of this enzyme can occur via the interaction of its N-terminal death effector domain with DEATH DOMAIN RECEPTOR SIGNALING ADAPTOR PROTEINS.
A long pro-domain caspase that contains a caspase recruitment domain in its pro-domain region. Caspase 9 is activated during cell stress by mitochondria-derived proapoptotic factors and by CARD SIGNALING ADAPTOR PROTEINS such as APOPTOTIC PROTEASE-ACTIVATING FACTOR 1. It activates APOPTOSIS by cleaving and activating EFFECTOR CASPASES.

Feline immunodeficiency virus (FIV) as a model for study of lentivirus infections: parallels with HIV. (6/51)FIV is a significant pathogen in the cat and is, in addition, the smallest available natural model for the study of lentivirus infections. Although divergent at the amino acid level, the cat lentivirus has an abundance of structural and pathophysiological commonalities with HIV and thus serves well as a model for development of intervention strategies relevant to infection in both cats and man. The following review highlights both the strengths and shortcomings of the FIV/cat model, particular as regards development of antiviral drugs. (+info)

Aspartic protease - Wikipedia
Aspartic proteases are a catalytic type of protease enzymes that use an activated water molecule bound to one or more aspartate residues for catalysis of their peptide substrates. In general, they have two highly conserved aspartates in the active site and are optimally active at acidic pH. Nearly all known aspartyl proteases are inhibited by pepstatin. Aspartic endopeptidases EC 3.4.23. of vertebrate, fungal and retroviral origin have been characterised. More recently, aspartic endopeptidases associated with the processing of bacterial type 4 prepilin and archaean preflagellin have been described. Eukaryotic aspartic proteases include pepsins, cathepsins, and renins. They have a two-domain structure, arising from ancestral duplication. Retroviral and retrotransposon proteases (retroviral aspartyl proteases) are much smaller and appear to be homologous to a single domain of the eukaryotic aspartyl proteases. Each domain contributes a catalytic Asp residue, with an extended active ...

SMART: Pfam domain A1 Propeptide
This entry represents the N-terminal domain of the aspartic peptidases. Aspartic peptidase, also known as aspartyl proteases ([intenz:3.4.23.-]) are a widely distributed family of proteolytic enzymes [ (PUBMED:6795036) (PUBMED:2194475) (PUBMED:1851433) ] known to exist in vertebrates, fungi, plants, retroviruses and some plant viruses. Aspartate proteases of eukaryotes are monomeric enzymes which consist of two domains. Each domain contains an active site centred on a catalytic aspartyl residue. The two domains most probably evolved from the duplication of an ancestral gene encoding a primordial domain. Currently known eukaryotic aspartyl proteases are: ...

Identification of proteases employed by dendritic cells in the processing of protein purified derivative (PPD) | Journal of...
Dendritic cells (DC) are known to present exogenous protein Ag effectively to T cells. In this study we sought to identify the proteases that DC employ during antigen processing. The murine epidermal-derived DC line Xs52, when pulsed with PPD, optimally activated the PPD-reactive Th1 clone LNC.2F1 as well as the Th2 clone LNC.4k1, and this activation was completely blocked by chloroquine pretreatment. These results validate the capacity of XS52 DC to digest PPD into immunogenic peptides inducing antigen specific T cell immune responses. XS52 DC, as well as splenic DC and DCs derived from bone marrow degraded standard substrates for cathepsins B, C, D/E, H, J, and L, tryptase, and chymases, indicating that DC express a variety of protease activities. Treatment of XS52 DC with pepstatin A, an inhibitor of aspartic acid proteases, completely abrogated their capacity to present native PPD, but not trypsin-digested PPD fragments to Th1 and Th2 cell clones. Pepstatin A also inhibited cathepsin D/E activity

Novel Aspartic Proteinase of the PepSIN Family (Napsin A, or NAPSA) belongs to the peptidase A1 family and plays a role in pneumocyte surfactant processing. It is also known as aspartyl protease 4 (ASP4), KAP, Kdap, napsin-1, NAP1, NAPA, and SNAPA. Two closely related proteins are known, Napsin A and Napsin B. Napsin A is a single-chain, 38-kDa protein. It is expressed at high levels in human lung and kidney, and at lower levels in spleen. Napsin A expression has been detected in type II pneumocytes and in lung adenocarcinomas.. ...
Protease LASSO Screening Libraries / Protease Libraries / Targeted and Focused Screening Libraries | Life Chemicals
Inhibition of HIV protease (HIVPR) or HIV reverse transcriptase (HIVRT) are two approaches to block viral replication. HIVPR is an aspartic acid protease that cleaves newly synthesized polyproteins at the appropriate places to create the mature protein components of an infectious HIV virion. Inhibition of its activity disrupts HIVs ability to replicate and infect additional cells. HIVRT is an RNA-dependent DNA polymerase that catalyzes the conversion/transcription of single-stranded RNA into DNA. Normal transcription involves the synthesis of RNA from DNA; hence, reverse transcription is the reverse of this. Discovery of small molecule inhibitors of these targets is facilitated by the use of ligand and receptor based screening using two different targeted libraries available from Life Chemicals available:. ...

Design and Synthesis of Inhibitors Targeting the Aspartic Proteases HIV-1 PR and BACE-1
This thesis describes the synthesis of molecules designed for inhibition of two aspartic proteases, viral HIV-1 PR and human BACE-1. It also reports on the structure activity relationships of the targeted enzyme inhibitors.. It is estimated that currently 33 million people are infected with HIV, the causative agent of AIDS. The virus targets T-lymphocytes and macrophages of the human immune system. The HIV-1 PR plays an important role in the viral replication, and by inhibiting the enzyme the disease progression can be slowed down or even halted.. Herein is reported the design and synthesis of a series of HIV-1 PR inhibitors with novel P2 substituents of which several inhibit the enzyme in the nanomolar range. The aim of the second work was to further develop the inhibitors by the introduction of fluorine. Several attempts were performed to fluorinate different P2-substituents.. Alzheimers disease (AD) is neurodegenerative, progressive and fatal disorder of the brain. It is associated with ...

Protease - GyDB org
LTR retroelement-like proteases (PRs, also named here as APs) are proteolytic enzymes that play a key role in the maturation process during which several peptides involved in the life cycle of the retroelement are scissed by this enzyme. LTR retroelement PRs belong to clan AA of aspartic peptidases (Rawlings et al. 2008); they dimerize in their active form and may be encoded as a part of the pol polyprotein, alone or as a part of the gag polyprotein, or in frame with a dUTPase (see dUTPase section). It is well known that the structural PR homodomain is founded in a core ~90-150 residues long wherein the catalytic DTG motif (Pearl and Blundell 1984) is the most prominent feature along with a glycine at the C-terminal end preceded by two hydrophobic residues (Pearl and Taylor 1987). At the primary structure level the most conserved part (core) of all clan peptidases may be divided in six amino acidic patterns constituting a template we have called DTG/ILG. We introduce this template in a ...
The Toxoplasma Blog: Aspartic Proteases and a Novel, Dynamic and Cell-Cycle-Dependent Protease Localization in Toxo
Aspartic proteases are important virulence factors in pathogens like HIV, Candida albicans or Plasmodium falciparum. We report here the identification of seven putative aspartic proteases, TgASP1 to TgASP7, in the apicomplexan parasite Toxoplasma gondii. Bioinformatic and phylogenetic analysis of the TgASPs and other aspartic proteases from related Apicomplexa suggests the existence of five distinct groups of aspartic proteases with different evolutionary lineages. The members of each group share predicted biological features that validate the phylogeny. TgASP1 is expressed in tachyzoites, the rapidly dividing asexual stage of T.gondii. We present the proteolytic maturation and subcellular localization of this protease through the cell cycle. TgASP1 shows a novel punctate localization associated with the secretory system in non-dividing cells, and relocalizes dramatically and unambiguously to the nascent inner membrane complex of daughter cells at replication, before coalescing again at the end ...

Cascade synthesis with (triphenylphosphoranylidene)ethenone as a versatile reagent for fast synthesis of heterocycles and...
Today, the demand for speed in drug discovery is constantly increasing, particularly in the iterative processes of hit validation and expansion and lead optimization. Irradiation with microwaves (MWs) has been applied in the area of organic synthesis to accelerate chemical reactions and to facilitate the generation of new chemical entities since 1986. In the work presented in this thesis, the use of MW-mediated heating has been expanded to address three fields of drug discovery, namely hit expansion, chemical library generation and genomics.. In the first project, potential inhibitors of malaria aspartic proteases were designed and synthesized, partly by MW-assisted organic chemistry, and evaluated with regard to their inhibitory efficacy on five malaria aspartic proteases and their selectivity over two human aspartic proteases. The synthetic work included the development of fast and convenient methods of MW-assisted formation of thiazolidines and epoxy esters. Some of the resulting structures ...

Plasmodium falciparum - encyclopedia article - Citizendium
A lot of research is being done on Plasmodium falciparum in order to get rid of the disease. Researchers are hoping to discover new drugs and vaccines that could treat the disease or remove it entirely from the world. Researchers have been trying to find a new drug that would terminate the function of an important enzyme used by P. falciparum. They would like to discover a drug that can inhibit plasmepsins I and II, Plm I and Plm II. In P. falciparum, Plm I is the first to cleave the hemoglobin. Plm II also cleaves but it mainly takes action against denatured hemoglobin. Plm I and Plm II is said to be homologous to aspartic acid proteases, such as Cathepsin D (Cat D) in mammals. It would good if researchers can find an antimalarial drug that can stop Plm I from breaking down hemoglobin so that the P. falciparum parasite can die. Pepstatin A inhibits aspartic protease and prevents hemoglobin degradation. So this might be a successful drug. Researchers are also in the process of creating ...
An n →π* Interaction in the Bound Substrate of Aspartic Proteases Replicates the Oxyanion Hole
Aspartic proteases regulate many biological processes and are prominent targets for therapeutic intervention. Structural studies have captured intermediates along the reaction pathway, including the Michaelis complex and tetrahedral intermediate. Using a Ramachandran analysis of these structures, we discovered that residues occupying the P1 and P1′ positions (which flank the scissile peptide bond) adopt the dihedral angle of an inverse γ-turn and polyproline type-II helix, respectively. Computational analyses reveal that the polyproline type-II helix engenders an n→π∗ interaction in which the oxygen of the scissile peptide bond is the donor. This interaction stabilizes the negative charge that develops in the tetrahedral intermediate, much like the oxyanion hole of serine proteases. The inverse γ-turn serves to twist the scissile peptide bond, vacating the carbonyl π∗ orbital and facilitating its hydration. These previously unappreciated interactions entail a form of ...

A novel, obligately anaerobic, mesophilic, haloalkaliphilic spirochaete, strain ASpG1T, was isolated from sediments of the alkaline, hypersaline Mono Lake in California, USA. Cells of the Gram-negative strain were motile and spirochaete-shaped with sizes of 0·2-0·22×8-18 μm. Growth of the strain was observed between 10 and 44 °C (optimum 37 °C), in 2-12 % (w/v) NaCl (optimum 3 % NaCl) and between pH 8 and 10·5 (optimum pH 9·5). The novel strain was strictly alkaliphilic, required high concentrations of carbonates in the medium and was capable of utilizing d-glucose, fructose, maltose, sucrose, starch and d-mannitol. End products of glucose fermentation were H2, acetate, ethanol and formate. Strain ASpG1T was resistant to kanamycin and rifampicin, but sensitive to gentamicin, tetracycline and chloramphenicol. The G+C content of its DNA was 58·5 mol%. DNA-DNA hybridization analysis of strain ASpG1T with its most closely related species, Spirochaeta alkalica Z-7491T, revealed a hybridization value

Plasmepsin - Wikipedia
Plasmepsins are a class of at least 10 enzymes (EC 184.108.40.206 and EC 220.127.116.11) produced by the Plasmodium falciparum parasite. There are ten different isoforms of these proteins and ten genes coding them respectively in Plasmodium (Plm I, II, III, IV, V, VI, VII, IX, X and HAP). It has been suggested that the plasmpesin family is smaller in other human Plasmodium species. Expression of Plm I, II, IV, V, IX, X and HAP occurs in the erythrocytic cycle, and expression of Plm VI, VII, VIII, occurs in the exoerythrocytic cycle. Through their haemoglobin-degrading activity, they are an important cause of symptoms in malaria sufferers. Consequently, this family of enzymes is a potential target for antimalarial drugs. Plasmepsins are aspartic acid proteases, meaning their active site contains two aspartic acid residues. These two aspartic acid residue act respectively as proton donor and proton acceptor, catalysing the hydrolysis of peptide bond in proteins. There are four types of plasmepsins, closely ...
A fourth secreted aspartyl proteinase gene (SAP4) and a CARE2 repetitive element are located upstream of the SAP1 gene in...
Candida albicans secreted aspartyl proteinases (Sap), products of the SAP genes, which are presumed to act as virulence factors. In the C. albicans strain WO-1, the ability to secrete Sap1 is regulated with switch phenotype, another putative virulence factor. KpnI restriction fragment length polymorphisms differentiate between several distinct SAP1 alleles in laboratory and clinical strains. Both SAP1 alleles from strain WO-1 along with their 5- and 3-flanking regions were cloned and sequenced, as were both alleles from another strain, SS. The 5-flanking regions were remarkably similar in all four of the sequenced alleles over approximately 1,500 nucleotides. S1 analysis revealed that both alleles of WO-1 are transcribed. Characterization of the one allele from strain WO-1 identified a 284-nucleotide insertion flanked by 8-bp direct repeats that shows homology to the CARE2 repetitive element and that is not present in the other alleles. Characterization of the SAP1 alleles also identified a ...

is one of the three main causative agents of human schistosomiasis, a major health problem with a vast socio-economic impact. Recent advances in the proteomic analysis of schistosomes have revealed that peptidases are the main virulence factors involved in the pathogenesis of this disease. In this context, evolutionary studies can be applied to identify peptidase families that have been expanded in genomes over time in response to different selection pressures. Using a phylogenomic approach, we searched for expanded endopeptidase families in the S. mansoni predicted proteome with the aim of contributing to the knowledge of such enzymes as potential therapeutic targets. We found three endopeptidase families that comprise leishmanolysins (metallopeptidase M8 family), cercarial elastases (serine peptidase S1 family) and cathepsin D proteins (aspartic peptidase A1 family). Our results suggest that the Schistosoma members of these families originated from successive gene duplication events in the ...

Renin activates the renin-angiotensinsystem by cleaving angiotensinogen, produced by the liver, to yield angiotensinI, which is further converted into angiotensin II by ACE, theangiotensin-converting enzyme primarily within the capillaries of the lungs. Ithas been reported that the levels of circulating prorenin (but not renin) areincreased in diabetic subjects.

No, I am not one. But I did apply today for the course here in DC. Interviews are in December, and the course is in February and March. 2.5 hours every Tuesday and Thursday night. Geez! The 50 hours of volunteering afterward is much easier to swallow--I volunteer anywhere from five to 15 hours in any given week anyway (an average of about six or seven, however--15 is peak time, which has been in June and December for me here), three or four of which is at a Master Gardener-approved volunteering place already (the Youth Garden).
