- Characterisation of the hydrolytic specificity of Aspergillus niger derived prolyl endoproteinase on bovine β-casein and determination of ACE inhibitory activity.
- Norris R1, Poyarkov A2, O'Keeffe MB1, Fitzgerald RJ3.Author information 1Department of Life Sciences, University of Limerick, Ireland.2Department of Life Sciences, University of Limerick, Ireland; Food for Health Ireland, University of Limerick, Ireland.3Department of Life Sciences, University of Limerick, Ireland; Food for Health Ireland, University of Limerick, Ireland. Electronic address: dick.fitzgerald@ul.ie.AbstractThe hydrolytic specificity of Aspergillus niger prolyl endoproteinase (An-PEP) on purified β-casein (β-CN) was assessed. This analysis confirmed cleavage at the C-terminal side of Pro residues. An-PEP also had the ability to cleave at the C-terminal side of Ala, Glu, Gly, Ser, Lys and Leu. Incubation of purified β-CN with An-PEP resulted in the generation of highly potent angiotensin converting enzyme (ACE) inhibitory hydrolysates. The most potent hydrolysate was obtained after 24h incubation (ACE IC50=16.41±6.06μg/mL). Fourteen β-CN derived C-terminal Pro-containing di-, tri, and tetrapeptides which were predicted in silico to be released following An-PEP hydrolysis or which were detected by ultra-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) in the 24h hydrolysate were synthesised and characterised for their ACE inhibitory activity. The most potent inhibitory peptides were Ile-Gln-Ala (β-CN f187-189) and Val-Glu-Pro (β-CN f116-118) having ACE IC50 values of 32.9±9.2 and 63.7±12.0μM, respectively. The hydrolysates generated appear to have the most potent ACE IC50 values reported for a food derived hydrolysate to date.

- Identification of peptides from soybean protein, glycinin, possessing suppression of intracellular Ca2+ concentration in vascular smooth muscle cells.
- Kumrungsee T1, Wang ZQ1, Matsumura S1, Saiki T1, Tanaka M1, Matsui T2.Author information 1Department of Bioscience and Biotechnology, Division of Bioresource and Bioenvironmental Sciences, Faculty of Agriculture, Graduated School of Kyushu University, 6-10-1 Hakozaki, Fukuoka 812-8581, Japan.2Department of Bioscience and Biotechnology, Division of Bioresource and Bioenvironmental Sciences, Faculty of Agriculture, Graduated School of Kyushu University, 6-10-1 Hakozaki, Fukuoka 812-8581, Japan. Electronic address: tmatsui@agr.kyushu-u.ac.jp.AbstractIn this study, we challenged to identify vasoactive peptides in soybean 11S glycinin hydrolysate by thermolysin to regulate intracellular Ca(2+) concentration ([Ca(2+)]i) that can induce constrictive vascular tension. As a function of the inhibition of elevated [Ca(2+)]i by 10 μM angiotensin (Ang) II in vascular smooth muscle cells (VSMCs), eleven peptides were successfully identified from the hydrolysate, among which His-Gly-Lys exhibited the most potent inhibition against [Ca(2+)]i elevation in Ang II-stimulated VSMCs (inhibition at 300 μM: 46.5±8.0% vs. control). The biological capacity of His-Gly-Lys analogues as an [Ca(2+)]i inhibitor was also proven when His-Lys and His-Gly-Arg elicited a significant reduction in [Ca(2+)]i. In contrast, less reduction of [Ca(2+)]i by His-Gly-Ile and His-(3-methyl)-Gly-Lys indicated the importance of the imino proton in His, along with basic amino acids positioned at C-terminal for the effect.

- Anti-inflammatory cyclopeptides from exocarps of sugar-apples.

Electronic address: wxy@scbg.ac.cn.AbstractTwo new cyclic peptides, fanlizhicyclopeptide A, cyclo(Pro(1)-Pro(2)-Tyr(3)-Leu(4)-Pro(5)-Gly(6)-Val(7)) (1), and fanlizhicyclopeptide B, cyclo(Pro(1)-Ile(2)-Tyr(3)-Ala(4)-Gly(5)) (2), were isolated along with six known kaurane diterpenoids and a known clovane sesquiterpene from the exocarps of sugar-apples, the fruit of Annona squamosa. Their structures were elucidated by ESI MS/MS experiments, 1D and 2D NMR data and chemical degradation. In the anti-inflammatory assay, both 1 and 2 showed in vitro inhibitory effects on the production of pro-inflammatory cytokines, TNF-α and IL-6, in LPS-stimulated RAW 264.7 macrophages.

- L-アミノ酸、D-アミノ酸がある。一般的に生合成されるポリペプチドはL-アミノ酸を材料としている。D-アミノ酸は細菌が産生し、ごく短いペプチドとして特に、細胞壁に存在する。これはペプチダーゼによる分解を免れるためと言われている。D-アミノ酸を含むポリペプチドは、通常の翻訳経路で生合成されない。(FB.58)
