adenine-bound MTAN1 is exclusively in its closed form, substantial conformational changes occur in this region during the enzymatic reaction. Residues Met35, Val90, Leu181, Met201, Phe237 and Ile143', Ile145' and Phe148' in a neighboring MTAN1 monomer bind adenine via hydrophobic and van der Waals interactions. The hydrophobic side chains Phe237 and Leu181 show structural perturbations that provide the flexible accommodation of the adenine ring. The carboxylic side chain of Asp225 hydrogen bonds with nitrogen atoms in the adenine ring, therefore being key determinant for the adenine base. The side chain Thr116 and backbone Gly118 also interact with the adenine molecule

adenine + 5-methylthio-D-ribose 1-phosphate
hydrolysis of 5'-methylthioadenosine predominates despite MTAN2 possessing both 5'-methylthioadenosine and S-adenosylhomocysteine hydrolysis activity. MTAN2 binds 5'-methylthioadenosine approximately 6fold higher than S-adenosylhomocysteine. Residues between 216 and 225 in MTAN2 contain conformational differences representing an open conformation when compared with MTAN1. The side chains Met22, Val78, Met168, Met188, Phe224 along with Ile130', Val132' and Leu135' in a neighboring MTAN2 monomer bind adenine via hydrophobic and van der Waals interactions. The hydrophobic side chains Phe224 and Met168 show structural perturbations that provide the flexible accommodation of the adenine ring. The carboxylic side chain of Asp211 hydrogen bonds with nitrogen atoms in the adenine ring, therefore being key determinant for the adenine base. The side chain Thr103 and backbone Gly105 also interact with the adenine molecule

the [3'-2H] kinetic isotope effect is consistent with a unique H3'-endo-exo configuration and 3'-hydroxyl polarization without full ionization at the MTAN transition state. The MTAN transition state is a fully dissociative (SN1), ribooxacarbenium-like structure with its C1'-N9 distance larger than 3.2 A. The ribosyl moiety adopts a H3'-endo-exo transition conformation, and the 3'-OH residue is partially polarized by the adjacent carboxylate with a hydrogen bond distance of 2.83 A. The MTAN transition state has a geometry between the unrestrained H3'-endo 5'-methylthioadenosine substrate and a fully developed 3'-exo ribooxacarbenium ion

calcineurin B-like 3
inhibits only in the presence of Ca2+, MTAN interacts specifically with calcineurin B-like 3, but not with calcineurin B-like 1 and calcineurin B-like 4. The 91-amino acid region of calcineurin B-like 3 is sufficient for the interaction with MTAN. Calcineurin B-like 3 and MTAN associate with each other in plant cells, they interact in vitro and in vivo, form a complex outside of the nucleus, colocalize mainly at the plasma membrane

5'-butylthio-DADMe-ImmucillinA
-
inhibits autoinducer-2 production in enterohemorrhagic strain O157:H7 and MTAN knockout strain. Inhibition of autoinducer-2 production in both strains persists for several generations, and causes reduction in biofilm formation. Strong binding to MTAN, causes no growth defects of O157:H7 and MTAN knockout strain in the presence of up to 0.0005 mM, produces the same phenotype as the MTAN- strain
