Common Name(2R,4S)-2-Methyl-2,3,3,4-tetrahydroxytetrahydrofuran
Description(2R,4S)-2-methyl-2,3,3,4-tetrahydroxytetrahydrofuran, also known as autoinducer 2 (AI-2), is a member of the chemical class known as Oxolanes. These are organic compounds containing an oxolane (tetrahydrofuran) ring, which is a saturated aliphatic five-member ring containing one oxygen and five carbon atoms. AI-2 is the R isomer of 2-methyl-2,3,3,4-tetrahydroxytetrahydrofuran, so it can be abbreviated as (R)-THMF. Autoinducer 2 (AI-2), a quorum sensing signaling molecule proposed to be involved in interspecies communication, is produced by many species of gram-negative and gram-positive bacteria including E. coli. (PMID 19636340 , 15601708 , 18256823 ) AI-2 is spontaneously derived from 4,5-dihydroxy-2,3-pentanedione that, along with homocysteine, is produced by cleavage of S-adenosylhomocysteine (SAH) and S-ribosylhomocysteine by the Pfs and LuxS enzymes. (PMID 16885435 ) Both LsrB and Tsr are necessary for sensing AI-2. LsrB binds AI-2 in the periplasm, and Tsr is the L-serine chemoreceptor. (PMID 21097621 )
