Modification of recombinant human epidermal growth factor (rh-EGF) expression vector by site-directed mutagenesis for therapeutic protein production

open access: yesIndonesian Journal of Biotechnology, 2019
Recombinant human epidermal growth factor (rh-EGF) has high value in therapies for h-EGF deficiency-related diseases. The expression of the h-EGF gene was designed by using the pET21b(+) vector and Escherichia coli BL21(DE3) as the expression host.

The Human Pregnancy-Specific Glycoprotein Genes are Tightly Linked on the Long Arm of Chromosome 19 and are Coordinately Expressed [PDF]

open access: yes, 1990
The pregnancy-specific glycoprotein (PSG) genes encode a group of proteins which are found in large amounts in placenta and maternal serum. In situ hybridization analyses of metaphase chromosomes reveal that all the human pregnancy-specific glycoprotein (

Membralin Assembles a MAN1B1–VCP Complex to Target Foreign Glycoproteins from the Endoplasmic Reticulum to Lysosomes for Degradation

open access: yesAdvanced Science, EarlyView.
This study identifies Membralin as an ER‐phagy receptor that recruits MAN1B1 and VCP to form a selective ERLAD complex. By sensing dense N‐glycan clusters on viral fusion glycoproteins, this ubiquitin‐independent pathway directs SARS‐CoV‐2 spike, Ebola GP, influenza HA, and HIV‐1 Env to lysosomal degradation, thereby limiting viral infectivity ...

Modulating Restriction Endonuclease Activities and Specificities Using Neutral Detergents

open access: yesBioTechniques, 1999
It is well known that type II restriction enzyme activities and specificities can be modulated by altering solution conditions. The addition of co-solvents such as dimethyl sulfoxide (DMSO), alcohols and polyols can promote star activity, which is the ...

Natural Variations of ZmRLR1 Mediate the Root Lodging Resistance of Maize by Regulating Root Ascorbate and Auxin Homeostasis

open access: yesAdvanced Science, EarlyView.
Root lodging severely limits crop yield and quality. We reveal that ZmRLR1, a plasma membrane b‐type cytochrome, regulates lodging resistance in maize through dual roles: modulating intracellular redox balance and functioning as a novel component of clathrin‐mediated endocytosis to influence auxin homeostasis. Moreover, natural variations in the ZmRLR1

A novel platform for the production of nonhydroxylated gelatins based on the methylotrophic yeast Hansenula polymorpha [PDF]

open access: yes, 2007
The use of yeast as a host for heterologous expression of proteins that are normally derived from animal tissue is a promising way to ensure defined products that are devoid of potential harmful animal side products.

Emergence of Staphylococcus aureus Resistance to Antimicrobial Peptides Nisin, NZ2114 and Bacitracin Involves Multiple Phenotypic Changes

open access: yesAnimal Research and One Health, EarlyView.
The AMP‐induced mutant Staphylococcus aureus strain nzR showed increased resistance, five gene mutations, and decreased surface anion levels. AMPs affect the NDH‐2 protein encoded by ndh gene inhibiting the growth of S. aureus. The deletion of the ndh gene promotes the development of AMPs resistance.

BacS: An Abundant Bacteroid Protein in \u3cem\u3eRhizobium etli\u3c/em\u3e Whose Expression Ex Planta Requires \u3cem\u3enifA\u3c/em\u3e [PDF]

open access: yes, 2003
Rhizobium etli CFN42 bacteroids from bean nodules possessed an abundant 16-kDa protein (BacS) that was found in the membrane pellet after cell disruption. This protein was not detected in bacteria cultured in tryptone-yeast extract.

Targets for the MalI repressor at the divergent Escherichia coliK-12malX-malI promoters [PDF]

open access: yes, 2010
Random mutagenesis has been used to identify the target DNA sites for the MalI repressor at the divergent Escherichia coli K-12 malX-malI promoters. The malX promoter is repressed by MalI binding to a DNA site located from position -24 to position -9 ...

Engineered Stable, Antibiotic‐Free, High‐Level Protein Expression in the Probiotic Chassis Escherichia coli Nissle 1917

open access: yesBiotechnology and Bioengineering, EarlyView.
The probiotic E. coli Nissle 1917 was engineered to enable stable and antibiotic free protein expression platforms using native plasmids. Further modification aids in the production of high‐level protein expression for antimicrobial secretion whose activity is comparable to industry standard E. coli BL21.
