Abstract
An imbalance in oxygen supply to cardiac tissues or formation of thrombus leads to deleterious results like pulmonary embolism, coronary heart disease and acute cardiac failure. The formation of thrombus requires clinical encounter with fibrinolytic agents including streptokinase, urokinase or tissue plasminogen activator. Irrespective to urokinase and tissue plasminogen activator, streptokinase is still a significant agent in treatment of cardiovascular diseases. Streptokinase, being so economical, has an important value in treating cardiac diseases in developing countries. This review paper will provide the maximum information to enlighten all the pros and cons of streptokinase up till now. It has been concluded that recent advances in structural/synthetic biology improved SK with enhanced half-life and least antigenicity. Such enzyme preparations would be the best thrombolytic agents.

Eur J Pharm Biopharm 2017; 126:27-39. [PMID: 28606596 DOI: 10.1016/j.ejpb.2017.06.008] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2016] [Revised: 05/30/2017] [Accepted: 06/07/2017] [Indexed: 01/06/2023]
Abstract
Bio-pharmaceuticals like antibodies, hormones and growth factors represent about one-fifth of commercial pharmaceuticals. Host candidates of growing interest for recombinant production of these proteins are strains of the genus Bacillus, long being established for biotechnological production of homologous and heterologous proteins. Bacillus strains benefit from development of efficient expression systems in the last decades and emerge as major industrial workhorses for recombinant proteins due to easy cultivation, non-pathogenicity and their ability to secrete recombinant proteins directly into extracellular medium allowing cost-effective downstream processing. Their broad product portfolio of pharmaceutically relevant recombinant proteins described in research include antibody fragments, growth factors, interferons and interleukins, insulin, penicillin G acylase, streptavidin and different kinases produced in various cultivation systems like microtiter plates, shake flasks and bioreactor systems in batch, fed-batch and continuous mode. To further improve production and secretion performance of Bacillus, bottlenecks and limiting factors concerning proteases, chaperones, secretion machinery or feedback mechanisms can be identified on different cell levels from genomics and transcriptomics via proteomics to metabolomics and fluxomics. For systematical identification of recurring patterns characteristic of given regulatory systems and key genetic targets, systems biology and omics-technology provide suitable and promising approaches, pushing Bacillus further towards industrial application for recombinant pharmaceutical protein production.

Highly effective renaturation of a streptokinase from Streptococcus pyogenes DT7 as inclusion bodies overexpressed in Escherichia coli. BIOMED RESEARCH INTERNATIONAL 2014; 2014:324705.

Abstract
The streptokinase (SK) is emerging as an important thrombolytic therapy agent in the treatment of patients suffering from cardiovascular diseases. We reported highly effective renaturation of a SK from S. pyogeness DT7 overexpressed in E. coli, purification, and biochemical characterization. A gene coding for the SK was cloned from S. pyogeness DT7. Because accumulation of active SK is toxic to the host cells, we have expressed it in the form of inclusion bodies. The mature protein was overexpressed in E. coli BL21 DE3/pESK under the control of the strong promoter tac induced by IPTG with a level of 60% of the total cell proteins. The activity of the rSK, renatured in phosphate buffer supplemented with Triton X-100 and glycerol, was covered with up to 41 folds of its initial activity. The purified of protein was identified with MALDI-TOF mass spectrometry through four peptide fragments, which showed 100% identification to the corresponding peptides of the putative SK from GenBank. Due to overexpression and highly effective renaturation of large amounts of inclusion bodies, the recombinant E. coli BL21 DE3/pESK system could be potentially applied for large-scale production of SK used in the therapy of acute myocardial infarction.

[PMID: 24011469 PMCID: PMC3847498 DOI: 10.1186/1475-2859-12-78] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2013] [Accepted: 09/04/2013] [Indexed: 11/10/2022] Open
Abstract
Background Mannanase is an enzyme that can catalyze random hydrolysis of beta-1,4-mannosidic linkages in the main chain of mannans, glucomannans and galactomannans which are the key polymers in hemicellulose. It has been used in a number of different industrial applications including food, feed, pharmaceutical, pulp/paper industries, and second generation biofuel. To optimize the expression system of mannanase Man23 gene, two kinds of vectors and host bacteria were determined and compared. Results Recombinants pHY-p43-man23 and pBPS-man23 were constructed and transferred into Bacillus subtilis WB600 and Brevibacillus brevis respectively. For mannanase Man23 gene, recombinant pHY-p43-man23 expressed in Brevibacillus brevis had higher production and activity. Compared to the wild-type Bacillus subtilis B23, the production of recombinant pHY-p43-man23 in B. brevis increased by 10 times and activity increased by 21.3%. pHY-p43-man23 in B. brevis had activity at the range of 20 ~ 70°C but its optimum temperature was 50°C and had activity from pH 4 ~ 10 but its optimum pH was around 7. This demonstrated the recombinant had improved stability as well. Conclusions Mannanase is an important industrial enzyme and combination of vector pHY-p43 and host Brevibacillus brevis is a novel expression system for a mannanase decoding gene. This work aims at exploring a better expression system of mannanase Man23 decoding gene for industrial application.

Abstract
Lactococcus lactis is a potential host for production of recombinant proteins, especially of therapeutic importance. However, in glucose-grown cultures, lowering of pH due to accumulation of lactic acid and the concomitant induction of acid tolerance response (ATR) may affect the recombinant protein produced. In this work, we have analyzed the effect of culture pH and the associated ATR on production of recombinant streptokinase. Streptokinase gene was cloned and expressed as a secretory protein in L. lactis under the control of P170 promoter. It was found to undergo degradation to form inactive products leading to low productivity. The extent of degradation and productivity of streptokinase was greatly influenced by the development of ATR, which was dependent on the pH of the culture and initial phosphate concentration of the medium. It was found that high pH and high initial phosphate concentration leads to suppression of ATR and this results in at least 2.5-fold increase in streptokinase productivity and significant decrease in degradation of streptokinase.

Abstract
Streptokinase is one of the major blood-clot-dissolving agents used in many medical treatments. With the cloned streptokinase gene (skc) available, production of the secreted streptokinase from various Bacillus subtilis strains was studied. The use of the six-extracellular-protease-deficient strain, WB600, greatly improved the production yield of the secreted streptokinase. A modified skc which has the original skc promoter and signal sequence replaced with the B. subtilis levansucrase promoter and signal sequence was also constructed. B. subtilis carrying either the wild-type or the modified skc produces streptokinase at a comparable level. Even with WB600 as the expression host, a C-terminally-processed streptokinase was also observed. Through region-specific combinatorial mutagenesis around the C-terminal processing sites, streptokinase derivatives resistant to C-terminal degradation were engineered. One of the derivatives showed a 2.5-fold increase in specific activity and would potentially be a better thrombolytic agent.

Abstract
A partial library of BclI-generated chromosomal DNA fragments from Streptococcus equisimilis H64A (Lancefield Group C) was constructed in Escherichia coli. Clones displaying either streptokinase or deoxyribonuclease (streptodornase; SDC) activities were isolated. The gene (sdc) expressing the SDC activity was allocated on the 1.1-kb AccI DNA subfragment. Sequence analysis of this DNA fragment revealed the presence of one open reading frame, which could encode a protein of 36.8 kDa. The N-terminal portion of the deduced protein exhibited features characteristic of prokaryotic signal peptides. The sdc gene was expressed in E. coli, Bacillus subtilis and Lactococcus lactis. As observed for S. equisimilis, in the heterologous Gram + hosts, at least part of the SDC protein was secreted into the medium.

Abstract
The human gene for mature interferon-alpha 1 (IFN-alpha 1) was inserted in a new transcription-translation fusion vector system based on the expression and secretion signals of the gene for type A streptococcal pyrogenic exotoxin, speA. As deduced from the known nucleotide sequences of the component elements, the encoded IFN-alpha 1 was a fusion protein carrying an N-terminal extension of 17 amino acids. When inserted in appropriate vectors capable of replication in Escherichia coli, Bacillus subtilis and Streptococcus sanguis, this expression configuration directed the synthesis of antiviral activity in all 3 organisms, as judged by the cythopathic effect inhibition assay of Vesicular Stomatitis Virus. In E. coli JM101, IFN activity was found mainly in the cytoplasmic protein fraction whereas in the gram-positive hosts, it was completely secreted into the culture medium.
