SAM riboswitches bind S-adenosyl methionine (SAM) to regulate methionine and SAM biosynthesis and transport. Three distinct SAM riboswitches are known: SAM-I (originally called S-box), SAM-II and the S MK box riboswitch. SAM-I is widespread in bacteria, but SAM-II is found only in Alpha-, Beta-, and a few Gammaproteobacteria.
SAM-V riboswitch is the fifth known riboswitch to bind S-adenosyl methionine (SAM). It was first discovered in the marine bacterium Candidatus Pelagibacter ubique and can also be found in marine metagenomes. [ 1] SAM-V features a similar consensus sequence and secondary structure as the binding site of SAM-II riboswitch, but bioinformatics ...
SAM-VI is a member of the riboswitch family. It is predominantly found in Bifidobacterium and exhibits some similarities to the SAM-III ( Smk box) riboswitch class, but lacks most of the highly conserved nucleotides of SAM-III class. SAM-VI aptamers bind the cofactor S-adenosylmethinine SAM (a key metabolite in sulphur metabolism) and ...

Infobox references. S-Adenosyl methionine (SAM), also known under the commercial names of SAMe, SAM-e, or AdoMet, is a common cosubstrate involved in methyl group transfers, transsulfuration, and aminopropylation. Although these anabolic reactions occur throughout the body, most SAM is produced and consumed in the liver. [1]
