Input: Consider Input:  Vibrio cholerae iron transport : haem transport genes are linked to one of two sets of tonB , exbB , exbD genes .

Output: exbD genes


Input: Consider Input:  It also showed which amino acid residues would contact an extended TATA box with a B recognition element , and evolutionary conservation of the TBP - TFB - DNA complex orientation between two archaeal organisms with widely different optimal temperature for growth ( 37 and 100 degrees C ) .

Output: B recognition element


Input: Consider Input:  Unlike these contaminant - responsive T cells , those that are truly specific for natural AChR epitopes appear less heterogeneous and therefore more suitable targets for selective immunotherapy .


Output: AChR epitopes
