Hepcidin-25 (hepatic bactericidal protein), also known as LEAP-1 (liver-expressed antimicrobial peptide), is found independently in human blood ultrafiltration and urine. It is mainly expressed in liver and belongs to a new family of small vertebrate antimicrobial peptides that contain 8 cysteine residues and has obvious antibacterial and antifungal activities. Hepcidin is the main human iron regulatory hormone, which can bind to iron exporter ferroportin and induce its internalization and degradation, thus blocking iron efflux from cells. Uses: Anti-infective agents. Alternative Names: LEAP-1 (human); H-Asp-Thr-His-Phe-Pro-Ile-Cys-Ile-Phe-Cys-Cys-Gly-Cys-Cys-His-Arg-Ser-Lys-Cys-Gly-Met-Cys-Cys-Lys-Thr-OH (Disulfide bridge: Cys7-Cys23, Cys10-Cys13, Cys11-Cys19, Cys14-Cys22); L-alpha-aspartyl-L-threonyl-L-histidyl-L-phenylalanyl-L-prolyl-L-isoleucyl-L-cysteinyl-L-isoleucyl-L-phenylalanyl-L-cysteinyl-L-cysteinyl-glycyl-L-cysteinyl-L-cysteinyl-L-histidyl-L-arginyl-L-seryl-L-lysyl-L-cysteinyl-glycyl-L-methionyl-L-cysteinyl-L-cysteinyl-L-lysyl-L-threonine (7->23),(10->13),(11->19),(14->22)-tetrakis(disulfide); Hepcidin Hepc25 (human); Hepcidin-25.

hepoxilin-epoxide hydrolase
Converts hepoxilin A3 into trioxilin A3. Highly specific for the substrate, having only slight activity with other epoxides such as leukotriene A4 and styrene oxide. Hepoxilin A3 is an hydroxy-epoxide derivative of arachidonic acid that is formed via the 12-lipoxygenase pathway. It is probable that this enzyme plays a modulatory role in inflammation, vascular physiology, systemic glucose metabolism and neurological function. In vertebrates, five epoxide-hydrolase enzymes have been identified to date: EC 3.3.2.6 (leukotriene-A4 hydrolase), EC 3.3.2.7 (hepoxilin-epoxide hydrolase), EC 3.3.2.9 (microsomal epoxide hydrolase), EC 3.3.2.10 (soluble epoxide hydrolase) and EC 3.3.2.11 (cholesterol 5,6-oxide hydrolase). Group: Enzymes. Synonyms: hepoxilin epoxide hydrolase; hepoxylin hydrolase; hepoxilin A3 hydrolase. Enzyme Commission Number: EC 3.3.2.7. CAS No. 122096-98-4.

This type-II membrane-associated serine peptidase has been implicated in cell growth and development. The enzyme has been shown to activate blood coagulation factor VII by cleavage of the Arg152?Ile153 peptide bound in BHK cells, thus indicating a possible role in the initiation of blood coagulation. There is no cleavage after aromatic or aliphatic residues. The occupancy of the S2 site is an absolute requirement for catalysis and a basic residue at that site is preferred to an aliphaticresidue. The nature of the residue at S3 also affects hydrolysis, with Gln being much more favourable than Ala. Belongs in peptidase family S1A. Group: Enzymes. Enzyme Commission Number: EC 3.4.21.106. CAS No. 112398-23-9. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-4101; hepsin; EC 3.4.21.106; 112398-23-9.
