Abstract

Anti-cholesterol and anti-oxidant play a crucial role to combat cardiovascular disease (CVD), due to formation of arterial plagues from oxidation of cholesterol. In the past decades, bioactive peptides demonstrating anti-cholesterol and anti-oxidant activities have emerged as the alternative drugs. In this study, acid soluble collagen was extracted from the skin of snakehead murrel and employed to induce secretion of collagenase by Bacillus licheniformis F11.4. The collagenases secreted were in turn used to produce peptides hydrolysate and were grouped in two distinct collagenase fractions, designated as fraction D and F. Peptides hydrolysate produced by the fraction D was found to demonstrate HMG-CoA inhibitor activity comparable to pravastatin and limited anti-oxidant activity. Meanwhile, peptides hydrolysate generated using the fraction F demonstrated anti-oxidant activity comparable to BHT (2mM), vitamin C (2mM), and vitamin E (2mM), but limited HMG-CoA activity. Combination of the fraction D and F resulted in substantial HMG-CoA inhibition and anti-oxidant activities.

Abstract

Many health related problems such as cardiovascular diseases are associated with the formation of excessive clot in the blood (thrombus). Approaches in cardiovascular disease treatment are preventing the formation or removing the thrombus. The present thrombolytic agents can be classified as plasminogen activators, fibrinolytic enzyme which directly degrades fibrinogen or fibrin and heparin type which act as thrombin inhibitor. Recently, microbial fibrinolytic enzymes of food origin receive more attention that leads to escalating efforts to explore traditional fermented foods as the natural sources. We have successfully isolated microorganism from Indonesian fermented soybean tofu dregs “Oncom” that secretes fibrinolytic enzyme. The microorganism identified as Stenotrophomonas sp. is unique because most of the reported fibrinolytic microorganism belongs to Bacillus sp. This isolate was found to produce extracellular fibrinolytic enzyme which could degrade fibrinogen and fibrin directly as determined by fibrinogen zymography and fibrin plate methods. More importantly, the 30-kD purified enzymes was found to demonstrate not only fibrin and fibrinogen degradation capabilities, but also acted as thrombin inhibitor as determined using specific substrates for thrombin. This is the first report of a fibrinolytic enzyme that demonstrates additional synergistic activities. This finding accentuates the importance of further development of the enzyme into a powerful agent to treat the thrombus-related disease effectively.

Abstract

Hepatitis B virus (HBV) infects human and causes chronic liver infection, leading to liver cirrhosis and hepatocellular carcinoma. HBV X (Hbx) protein is known to interact with tumor suppressor protein p53 and block its translocation into the nucleus. This study outlines the overproduction of Hbx protein from HBV subgenotype B3 in Escherichia coli BL21(DE3), including its purification and refolding. The gene encoding Hbx was first codon-optimized and inserted into pET16b. The recombinant plasmid was then transformed into E. coli BL21(DE3) as an expression host. Optimization of Hbx expression was performed with variation of IPTG concentration and overproduction temperature. The results showed that Hbx protein was optimally induced by 0.075 mM IPTG and overproduction of Hbx at 17, 25, and 37°C exhibited no difference in protein level and location. The optimal refolding of Hbx was obtained using 0.1 M arginine prior to elution from Nickel column using 100 mM imidazole and 0.25 M arginine. Hbx migrates differently in SDS-PAGE reducing and non-reducing, while the melting curve pattern in TSA analysis changed after the refolding step. Essentially, this purified Hbx protein could potentially be used for interaction study with p53 and the inhibitor candidate of the protein.
