Also catalyzes the hydrolysis of 5'-methylthioadenosine (MTA) to adenine and 5'-methylthioribose. Can also probably use S-adenosylhomocysteine (SAH) as substrate, leading to adenine and S-ribosylhomocysteine. These other activities highlight the tremendous versatility of the enzyme, which also plays key roles in S-adenosylmethionine recycling and in the biosynthesis of the quorum-sensing molecule autoinducer-2.<ref>PMID:20954236</ref> <ref>PMID:22891633</ref>		[https://www.uniprot.org/uniprot/MQMTN_HELPJ MQMTN_HELPJ] Catalyzes the direct conversion of aminodeoxyfutalosine (AFL) into dehypoxanthine futalosine (DHFL) and adenine via the hydrolysis of the N-glycosidic bond; this reaction seems to represent an essential step in the menaquinone biosynthesis pathway in Helicobacter species.

-	== Publication Abstract from PubMed ==
-	Campylobacter and Helicobacter species express a 6-amino-6-deoxyfutalosine N-ribosylhydrolase (HpMTAN) proposed to function in menaquinone synthesis. BuT-DADMe-ImmA is a 36 pM transition state analogue of HpMTAN, and the crystal structure of the enzyme-inhibitor complex reveals the mechanism of inhibition. BuT-DADMe-ImmA has a MIC(90) value of <8 ng/mL for Helicobacter pylori growth but does not cause growth arrest in other common clinical pathogens, thus demonstrating potential as an H. pylori-specific antibiotic.

		+	== Publication Abstract from PubMed ==
		+	Campylobacter and Helicobacter species express a 6-amino-6-deoxyfutalosine N-ribosylhydrolase (HpMTAN) proposed to function in menaquinone synthesis. BuT-DADMe-ImmA is a 36 pM transition state analogue of HpMTAN, and the crystal structure of the enzyme-inhibitor complex reveals the mechanism of inhibition. BuT-DADMe-ImmA has a MIC(90) value of <8 ng/mL for Helicobacter pylori growth but does not cause growth arrest in other common clinical pathogens, thus demonstrating potential as an H. pylori-specific antibiotic.
