THE UNK CHAINS (A, E, C, G, 1-4) CORRESPONDING TO RAPTOR (A,E), SF FKBP AND RAPAMYCIN (C,G) AND THE N-TERMINAL HEAT REPEATS OF MTOR (1-4), HAVE BEEN NUMBERED FROM 100 AT EACH BREAK TO INDICATE LACK OF SEQUENCE - DENSITY CERTAINTY. CHAINS 1-4 CORRESPOND TO THE N-TERMINAL HEAT REPEAT DOMAINS OF MTOR. WE PROPOSE A TOPOLOGY IN THE CORRESPONDING PAPER (1-2-B AND 3-4-F), BUT GIVEN THE FACT THAT THEIR TOPOLOGY CANNOT BE ASSIGNED DEFINITIVELY THEY ARE REPRESENTED AS A SEPARATE CHAIN FOR EACH DOMAIN. THE FITTING OF CRYSTAL STRUCTURES FOR THE MTOR FAT AND PIKK DOMAINS, MLST8, RAPTOR AND FKBP ALLOWS THEIR DENSITY TO BE ASSIGNED DEFINITIVELY, AND THEIR CHAINS ARE THEREFORE LETTERED.
