产品说明
Product Code: ENZ-530Synonyms/Product Alternate Names: FKBP22, FKBP-14, FK506 Binding Protein 14, FKBP14, EC=5.2.1.8, PPlase FKBP14, Peptidyl-prolyl cis-trans isomerase FKBP14, FLJ20731.FKBP14 enzyme accelerates the folding of proteins during protein synthesis. FKBP14 contains 2 EF-hand domains and one PPIase FKBP-type domain. Truncation of the amino-terminus of FKBP14 significantly decreases peptidyl prolyl cis-trans isomerase activity, therefore implicating that the PPIase FKBP-type domain must be located at the N-terminus.Description: FKBP14 Recombinant E.coli produced in E.Coli is a single, non-glycosylated polypeptide chain containing 213 amino acids (20-211 a.a.) and having a molecular mass of 24.2 kDa. The FKBP14 is fused to 21 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.Physical Appearance: Sterile filtered colorless solution.Formulation: FKBP14 Human (1mg/ml) solution containing 1x PBS pH-7.4, & 10% glycerol.Stability: Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cyclesBiological Activity: Specific activity is > 240 nmoles/min/mg, and is defined as the amount of enzyme that cleaves 1umole of suc-AAFP-pNA per minute at 25°C in Tris-HCl pH8.0 using chymotrypsin.Origin: Escherichia Coli.Storage Conditions: -20 °CPurity: Greater than 90.0% as determined by SDS-PAGE.One-Letter Code:MGSSHHHHHH SSGLVPRGSH MALIPEPEVK IEVLQKPFIC HRKTKGGDLM LVHYEGYLEK DGSLFHSTHK HNNGQPIWFT LGILEALKGWDQGLKGMCVG EKRKLIIPPA LGYGKEGKGK IPPESTLIFN IDLLEIRNGP RSHESFQEMD LNDDWKLSKD EVKAYLKKEF EKHGAVVNESHHDALVEDIF DKEDEDKDGF ISAREFTYKH DELDelivery Details: All quantities are subject to availability.

现代营养学研究发现:人类摄食蛋白质经消化道的酶作用后,大多是以低肽形式消化吸收的,以游离氨基酸形式吸收的 比例很小。进一步的试验又揭示了肽比游离氨基酸消化更快、吸收更多,表明肽的生物效价和营养价值比游离氨基酸更高。这也正是活性肽的无穷魅力所在。
生物活性肽(Bioact ive Peptide s ,BA P)就是对生物机体的生命活动有益或是具有生理作用的肽类化合物, 是一类相对分子质量小于6000Da , 具有多种生物学功能的多肽。其分子结构复杂程度不一,是介于氨基酸与蛋白质之间的分子聚合物,小至由两个氨基酸组成,大至由数十个氨基酸通过肽键连接而成,而且这些多肽可通过磷酸化、糖基化或酰基化而被修饰 [1] 。
生物活性肽有多种多样的生理功能, 如激素作用、免疫调节、抗血栓、抗高血压、降胆固醇、抑菌、抗病毒、抗癌作用等 [2] 。这些功能是原蛋白质或组成氨基酸所不具备的独特的生理机能, 且许多活性肽的组成氨基酸并不一定是必需氨基酸,这就为利用蛋白质资源, 特别是那些原本认为生物效价不高的蛋白质资源利用提供了新的机遇,是当前国际食品界最热门的研究课题和极具发展前景的功能因子。20世纪末,科学家在破解基因的秘密的同时,也对存在于生物体内的另一类奇妙物质的研究发生极大的兴趣。这类物质就是生物活性肽,或称功能肽,由氨基酸组成,是一种小分子的蛋白质,比如胰岛素,就是一种多肽,再如在日本应用广泛的促进钙吸收的CCP,在欧美风靡一时的促进生长的HGH……。
