Collagen is the functional protein of skin, tendons, ligaments, cartilage, bone, and connective tissue. Due to its extraordinary properties, collagen has a wide range applications in biomedicine, tissue engineering, food, cosmetics. In this study, we designed fragment human type I (rhLCOL-I) expressed it Escherichia coli (E. coli) BL21(DE3) PlysS containing thermal-induced plasmid, pBV-rhLCOL-I...

Indolicidin is an antimicrobial cationic peptide naturally present in the bovine neutrophils. In this study, transformed Escherichia coli cells were employed for greater and cost effective production of indolicidin. Four strains of E. coli [C41 (DE3), C43 (DE3), C41 (DE3) pLysS & C43 (DE3) pLysS] were transformed with recombinant plasmid pET21A carrying the indolicidin gene and were successfull...

BACKGROUND The expression of heterologous proteins in Escherichia coli is strongly affected by codon bias. This phenomenon occurs when the codon usage of the mRNA coding for the foreign protein differs from that of the bacterium. The ribosome pauses upon encountering a rare codon and may detach from the mRNA, thereby the yield of protein expression is reduced. Several bacterial strains have bee...

Escherichia coli BL21(DE3) has long served as a model organism for scientific research, as well as a workhorse for biotechnology. Here we present the most current genome annotation of E. coli BL21(DE3) based on the transcriptome structure of the strain that was determined for the first time. The genome was annotated using multiple automated pipelines and compared to the current genome annotatio...

Background: The thriving of biodiesel industry has led to produce 10% (v/v) crude glycerol, thus creating an overflow problem. Biofuel production is restricted by Escherichia coli due to its toxicity to bacterial cells. Therefore, a platform chemical and fuel additive 2,3-butanediol (2,3-BD) with low toxicity to microbes could be a promising alternative for biofuel production by recombinant E. ...

When producing recombinant proteins, the use of Escherichia coli strain BL21(DE3) in combination with the T7-based pET-expression system is often the method of choice. In a recent study we introduced a mechanistic model describing the correlation of the specific glucose uptake rate (qs,glu) and the corresponding maximum specific lactose uptake rate (qs,lac,max) for a pET-based E. coli BL21(DE3)...

Background Tuberculosis remains the leading cause of death in the world, especially wherever poverty, malnutrition and poor housing prevail. Mycobacterium tuberculosis Beijing strain is the most common strain that causes tuberculosis in Indonesia. The wide spread of tuberculosis has been further aggravated by HIV-AIDS and drug resistance. Unfortunately, Bacille Calmette-Guerin (BCG) as the curr...

BACKGROUND Exogenous RNAs can specifically up-regulate or down-regulate gene expression after they enter into cells. Alu RNAs are the main constituent of human transcriptome and participate in gene expression regulation. AluY elements belong to a subfamily of Alus and are the youngest Alus. In this paper, we established the technology method of preparing genetically engineered humanized AluY RN...

Four exons of the human genomic GM-CSF gene were assembled together using gene splicing by overlap extension (SOE) method. The resulting nucleotide sequence was cloned in the pET23a(+) ex‌pression vector under the control of strong bacteriophage T7 transcription and translation signals. The construct obtained was Transferred into the E. coli strain, BL21(DE3) pLysS and IPTG was used for inducti...
