[https://www.uniprot.org/uniprot/MANA_CANEN MANA_CANEN] Liberates mannose from p-nitrophenyl-alpha-D-mannoside (PubMed:12325362, PubMed:4973951, PubMed:1156387). Liberates mannose from further alpha-D-mannosides including methyl-, benzyl-alpha-D-mannoside, 1-6-linked di-, tri- and tetrasaccharides of alpha-D-mannose and mannosyl-rhamnose (PubMed:12325362). Liberates mannose from various glycoproteins like ovalbumin and ovomucoid (PubMed:12325362, PubMed:5145). Does not hydrolyze beta-D-mannosides (PubMed:12325362). Has glycosyltransferase activity, forming disaccharides from mannose and lyxose but not from glucose, galactose, ribose, xylose or arabinose (PubMed:12325362).<ref>PMID:1156387</ref> <ref>PMID:12325362</ref> <ref>PMID:4973951</ref> <ref>PMID:5145</ref>

== Publication Abstract from PubMed ==
 +
Multivalent design of glycosidase inhibitors is a promising strategy for the treatment of diseases involving enzymatic hydrolysis of glycosidic bonds in carbohydrates. An essential prerequisite for successful applications is the atomic-level understanding of how outstanding binding enhancement occurs with multivalent inhibitors. Herein we report the first high-resolution crystal structures of the Jack bean alpha-mannosidase (JBalpha-man) in apo and inhibited states. The three-dimensional structure of JBalpha-man in complex with the multimeric cyclopeptoid-based inhibitor displaying the largest binding enhancements reported so far provides decisive insight into the molecular mechanisms underlying multivalent effects in glycosidase inhibition.
