An efficient one-step site-directed deletion, insertion, single and multiple-site plasmid mutagenesis protocol

open access: yesBMC Biotechnology, 2008
Background Mutagenesis plays an essential role in molecular biology and biochemistry. It has also been used in enzymology and protein science to generate proteins which are more tractable for biophysical techniques.

A new approach to 'megaprimer' polymerase chain reaction mutagenesis without an intermediate gel purification step

open access: yesBMC Biotechnology, 2004
Background Site-directed mutagenesis is an efficient method to alter the structure and function of genes. Here we report a rapid and efficient megaprimer-based polymerase chain reaction (PCR) mutagenesis strategy that by-passes any intermediate ...

The carboxyl terminus in apolipoprotein E2 and the seven amino acid repeat in apolipoprotein E-Leiden: role in receptor-binding activity

open access: yesJournal of Lipid Research, 1998
Both apolipoprotein (apo) E2 and apoE-Leiden (tandem repeat of amino acids 121–127) are associated with type III hyperlipoproteinemia and bind defectively to low density lipoprotein receptors. Removing the carboxyl terminus of both variants (residues 192–

In silico Analysis and Site-directed Mutagenesis of Promoters

open access: yesBio-Protocol, 2017
In normal as in cancerous cells, gene expression is tightly regulated by transcription factors, which are responsible for up- or down-regulation of thousands of targets involved in different cell processes. Transcription factors can directly regulate the

Site-directed mutation of a laccase from Thermus thermophilus: Effect on the activity profile [PDF]

open access: yesArchives of Biological Sciences, 2012
A site-directed mutant R453T of a laccase from Thermus thermophilus HB27 (Tth-laccase) was constructed in order to investigate the effect on laccase catalytic properties. The mutated gene was cloned and overexpressed in Escherichia coli.

Improved immobilization of laccase on a glassy carbon electrode by oriented covalent attachment [PDF]

open access: yesArchives of Biological Sciences, 2014
A laccase from Thermus thermophilus HB27 was reported to be potentially useful in the design of a temperature controlled biofuel cell. For enhancing its application in different thermal conditions, we engineered a laccase-oriented immobilized ...

Current status and emerging frontiers in enzyme engineering: An industrial perspective

open access: yesHeliyon
Protein engineering mechanisms can be an efficient approach to enhance the biochemical properties of various biocatalysts. Immobilization of biocatalysts and the introduction of new-to-nature chemical reactivities are also possible through the same ...

Construction of Glycine Oxidase Mutant Libraries by Random Mutagenesis, Site Directed Mutagenesis and DNA Shuffling

open access: yesBio-Protocol, 2014
Glyphosate, a broad spectrum herbicide widely used in agriculture all over the world, inhibits 5-enolpyruvylshikimate-3-phosphate synthase in the shikimate pathway, and glycine oxidase (GO) has been reported to be able to catalyze the oxidative ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
