Crystal structure of an initiation factor bound to the 30S ribosomal subunit. // Science, 2001, Vol. 291, p. 498- 501.Canonaco MA , Calogero RA and Gualerzi CO ( 1986 ) Mechanism of translation initiation in prokaryotes. Evidence for a direct effect of IF2 on the activity of the 30S...
These results suggest that the ribosome is a regulatory node for cold stress responses and that STCH4 promotes an altered ribosomal composition and functions in low temperatures to facilitate the translation of proteins important for plant growth and survival under cold stress. CAS-1 JCR-Q1 SCIE ...

The translation step of protein synthesis takes place on ribosomes formed from two smaller subunits. Ribosomes are protein-making factories but are structurally different in eukaryotes and prokaryotes. Archaea and bacteria are prokaryotes, while eukaryotes include everything else, like plants...
In prokaryotes, the 16S rRNA is essential for recognizing the 5' end of mRNA and hence positioning it correctly on the ribosome. The 16S rRNA has a characteristic secondary structure in which half of the nucleotides are base-paired. The 16S rRNA sequence has been highly conserved and is ...
Energy-coupling factor (ECF) transporters are responsible for uptake of micronutrients in prokaryotes. The recently reported crystal structure of an ECF transporter RibU provided a foundation for understanding the structure and transport mechanism of ECF transporters. In the present study, molecular ...
Intrinsically sensitive to membrane tension, MscS channels from several prokaryotes have been extensively characterized and served as a prevailing model system for understanding physicochemical principles in mechanotransduction9. X-ray and cryo-electron microscopy (Cryo-EM) structures reveal that each protomer...
What are the enzymes involved in transcription? (a) What enzymes are involved with DNA replication? (b) What are their roles? Which DNA repair mechanism lacks a DNA polymerase enzyme? What are the enzymes involved in DNA replication in prokaryotes? Give the function of each enzym...
Double-helical structures that are formed by binding of small noncoding RNAs (sRNAs) provide RNase III targets, and regulate mRNA translation and/or stability12,13. The diversity of RNase III targets and the multiple actions of the enzyme in conjunction with sRNAs and other factors underscore ...
