Explore: Riboswitches

discuss only metabolite-binding riboswitches. Most known riboswitches occur in bacteria, but functional riboswitches of one type (the TPP riboswitch)

pre-queuosine1, a precursor to queuosine: PreQ1-I riboswitches, PreQ1-II riboswitches and PreQ1-III riboswitches. Queuosine biosynthesis genes have also been

riboswitches are structured RNA elements that regulate adjacent genes related to cobalamin metabolism in response to cobalamin binding. Riboswitches are

charged tRNA. These are considered by some to be a separate family of riboswitches but are significantly more complex than the previous class of attenuators

are capable of enzymatic function, while others such as microRNAs and riboswitches have regulatory roles. The DNA sequences from which such RNAs are transcribed

guaAB operon and resemble purine riboswitches. The riboswitches identified in M. florum can be classed as novel riboswitches as they deviate in sequence and

creation of artificial self-cleaving riboswitches, termed aptazymes, has also been an active area of research. Riboswitches are regulatory RNA motifs that change

(thiamine + ATP → TPP + AMP). The biosynthetic pathways are regulated by riboswitches. If there is sufficient thiamine present in the cell then the thiamine

translation, either by affecting stability or affecting cis-binding ability. Riboswitches have also been discovered. They are cis-acting regulatory RNA sequences

replication of retroviruses. Inverted repeats play an important role in riboswitches, which are RNA regulatory elements that control the expression of genes
