Description of mamAB operon gene functions

Gene AMB Number Cluster Membership Member of 28 genes list? (specific*/related**) Function Summary (Vesicle chain formation, and/or biomineralization) Gene Function
mamH amb0961 mamAB Related unknown N/A
mamI amb0962 mamAB Specific Vesicle, Chain Formation >Loss of mamI causes no membrane formation, gene product is localized onto chains
mamE amb0963 mamAB; mam Islet Related >Membrane-bound serine protease required for magnetite formation; might control the localization of other magnetosome proteins
mamJ amb0964 mamAB; mam Islet Specific Chain Formation >Proper magnetosome chain organization/assembly
mamK amb0965 mamAB; mam Islet Related Chain Formation >Required for proper magnetosome chain organization; *bacterial actin-like cytoskeleton protein required for proper alignment of the magnetosomes in a chain, shown to localize the mamI
mamL amb0966 mamAB; mam Islet Specific Vesicle, biomineralization >Crucial to mangneosome membrane creation, shown to be spread across the cell membrane and sometimes forms lines
mamM amb0967 mamAB Related >Biomineralization, involved in iron transport, magnetite nucleation, or establishement of the proper chemical enviornment for magnetite synthesis in the magnetosome
mamN amb0968 mamAB Related >Biomineralization, involved in iron transport, magnetite nucleation, or establishement of the proper chemical enviornment for magnetite synthesis in the magnetosome
mamO amb0969 mamAB Related >Biomineralization, involved in iron transport, magnetite nucleation, or establishement of the proper chemical enviornment for magnetite synthesis in the magnetosome
mamP amb0970 mamAB Related Biomineralization >Loss of mamP causes weak magnetic response, with large but fewer crystals
mamA amb0971 mamAB Related >Required for magnetosome activation; activation of vessicles
mamQ amb0972 mamAB; mam Islet Related >ORF; formation/maintenance of magnetosome membranes
mamR amb0973 mamAB Specific Chain formation, Biomineralization >ORF; plays a role in controlling both particle number and size of magnetite cyrstals
mamB amb0974 mamAB Related Vesicle, Biomineralization >Indirect role in magnetosome membrane invagination and biomineralization; magnetosome compartment formation
mamS amb0975 mamAB Specific unknown function N/A
mamT amb0976 mamAB Specific Biomineralization >Magnetite crystal growth; participates in different steps during magnetite synthesis
mamU amb0977 mamAB Related unknown function N/A
mamV amb0978 mamAB unknown function N/A N/A
