Abstract

Protein isolate was hydrolysed by Alcalase, thermolysin and trypsin. BBPH produced by Alcalase showed highest angiotensin-converting enzyme (ACE) inhibitory properties (IC₅₀: 52 µg/mL). Hydrolysates produced by Alcalase and thermolysin exhibited similar dipeptidyl peptidase-IV (DPP-IV) inhibitory activity (IC₅₀: 1.73 mg/mL), while low inhibitory activity was observed for hydrolysate produced by trypsin. BBPH also showed protective effect against oxidative stress with significant 2,2-diphenyl-1-picrylhydrazyl radical scavenging and ferrous chelating activity. Bioactive peptides of BBPH produced by thermolysin showed better resistance to simulated gastrointestinal digestion (SGID), while the DPP-IV and ACE inhibitory properties were significantly reduced. Molecular weight distribution showed significant reduction in peptides of the molecular weight range 200–400 Da in BBPH produced by Alcalase, after SGID. LC-ESI-TOF-MS and in silico analysis showed the presence of potential peptides with both ACE and DPP-IV inhibitory properties in BBPH produced by thermolysin.

班巴拉豆蛋白水解物抗氧化、血管紧张素转换酶和二肽基肽酶IV抑制活性的研究

分离蛋白经Alcalase、热溶酶和胰蛋白酶水解。Alcalase产生的BBPH具有最高的血管紧张素转换酶(ACE)抑制性能(IC50: 52 µg/mL)。Alcalase和thermolysin产生的水解液具有相似的二肽基肽酶- iv (DPP-IV)抑制活性(IC50: 1.73 mg/mL)，而胰蛋白酶产生的水解液抑制活性较低。BBPH还具有显著的2,2-二苯基-1-苦味酰肼自由基清除和铁螯合活性，对氧化应激具有保护作用。热溶素产生的BBPH生物活性肽对模拟胃肠消化(SGID)具有较好的抗性，而DPP-IV和ACE抑制性能显著降低。SGID后，Alcalase产生的BBPH中分子量在200-400 Da范围内的肽的分子量分布显著减少。LC-ESI-TOF-MS和硅质谱分析显示，热溶素产生的BBPH中存在具有ACE和DPP-IV抑制特性的潜在肽。
