As a complement, this approach was combined with a mutational analysis in which a collection of mutants obtained by random gene transposition was screened to identify differential gene expression in the presence of arsenic. A previous study has already led by such a procedure to the identification ...
Defensins are cationic AMP together with six conserved cysteine residues that form three intramolecular disulphide bridges. A gene related to defensin called BmDefensin A was discovered in the silkworm genome. BmDefensin A is highly transcribed in the haemocyte, silk gland, head, and ovary of the ...
Translation in prokaryotes and translation in eukaryotes are similar. However, in prokaryotes, translation occurs in concert with transcription, that is, translation takes place as the mRNA is still being synthesized. This is possible because prokaryotes have no nuclear membrane separating the two ...
In summary, we have demonstrated that cyclic nitrogenase gene expression persists under constant conditions, that the rhythms can be entrained to daily L-D cycles by L-D cues, and that the rhythms a...Kippert, F. (1991) Essential clock proteins/circadian rhythms in prokaryotes -- what is ...
Kac is one important types of PTM protein acylation and plays a key role in many cellular processes including gene transcription and cellular metabolism35. Kac is evolutionarily conserved from eukaryotes to prokaryotes36. Kac regulated the defense response to stress, such as stimuli stress, UV-...
RNA-binding proteins play key roles in controlling gene expression in many organisms, but relatively few have been identified and characterised in detail in Gram-positive bacteria. Here, we globally analyse RNA-binding proteins in methicillin-resistant S
TPRs occur as tandem repeats in a widespread protein family of both prokaryotes and eukaryotes. PPRs also occur in multiple tandem repeats, but have thus far been found to be exclusively eukaryotic in their distribution. On the basis of the solved structure of a TPR domain [2] as well as ...
Signaling pathways allow cells to detect and respond to a wide variety of chemical (e.g. Ca2+ or chemokine proteins) and physical stimuli (e.g., sheer stress, light). Together, these pathways form an extensive communication network that regulates basic c
The invention relates broadly to inhibiting translation and thus the synthesis of proteins. Under specified conditions, protein synthesis can be blocked in prokaryotes and in eukaryotes, hence inhibiting cell growth. Regulation of cell growth by artificially constructed antisense RNA against tRNAs has ne...
As a result of such a complicated production process, i.e., leptin purified from inclusion bodies made in prokaryotes, it may not be possible to provide a well-defined homogeneous protein sample with full biological activity. Attempts to improve the solubility of leptin have included mutating cert...
