Enzymes are the most proficient catalysts, offering much more competitive processes compared to chemical catalysts. The number of industrial applications for enzymes has exploded in recent years, mainly owing to advances in protein engineering technology and environmental and economic necessities. Herein, we review recent progress in enzyme biocatalysis,(More)
GFP and its derivatives are commonly used as non-invasive in vivo reporters. These fluorescent proteins have been employed to analyze expression level, localization and movement of proteins, as well as protein interaction. However, they cannot be utilized under anaerobic conditions due to the oxygen requirement for the maturation of the fluorophore. Thus,(More)
Although there is no sequence information, activity-based screening methods can select positive clones from a metagenomic library. However, the low frequency of positive hits that is caused by improper expression of proteins in the cloning host Escherichia coli might be improved. In order to investigate whether the metagenome can be expressed in E. coli,(More)
This study was focused on the screening of valuable genetic resources, such as promoters from metagenome, and describes a promoter trapping system with a bidirectional probe concept, which can select promoters or operons from various biological resources including metagenomic DNA. A pair of reporters, GFP and DsRed, facing the opposite direction without(More)
In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository. Authors requiring further information regarding Elsevier's archiving and manuscript policies are encouraged to visit: a b s t r a c t a r t i c l e i n f o In the high-temperature range, where the(More)
The nhhBAG gene of Rhodococcus rhodochrous M33 that encodes nitrile hydratase (NHase), converting acrylonitrile into acrylamide, was cloned and expressed in Corynebacterium glutamicum under the control of an ilvC promoter. The specific enzyme activity in recombinant C. glutamicum cells was about 13.6 μmol/min/mg dry cell weight (DCW). To overexpress the(More)
Fluorescent proteins that can be useful as indicators or reporters must have rapid maturation time, high quantum yield and photobleaching stability. A red fluorescent protein DsRed that has a high quantum yield and photostability has an innately slow maturation time when compared to other fluorescence proteins. In this study, we combined a functional(More)
The integration of a targeted delivery with a tumour-selective agent has been considered an ideal platform for achieving high therapeutic efficacy and negligible side effects in cancer therapy. Here, we present engineered protein nanoparticles comprising a tumour-selective oncolytic protein and a targeting moiety as a new format for the targeted cancer(More)
