Comments "With a conservative estimate of 100 different transport systems and an average of two components per system together with their regulatory genes the E. coli cell may devote as much as 10% of its coding capacity to ensure the proper exchange with its surroundings. Thus, transport systems may be regarded as part of the metabolic pathways of a given substrate, rather than separated entities of membrane function."
