ATP-binding cassette transport systems have high substrate affinity and thus help microorganisms survive in low nutrient environments.

Question

Quizplus · Accepted Answer

ATP-binding cassette transport systems are well known for their high substrate affinity, which enables microorganisms to survive in nutrient-depleted environments. This transport system utilizes ATP hydrolysis to drive the movement of various substrates across the cell membrane, including sugars, amino acids, vitamins, and peptides. The high substrate affinity provides a competitive advantage to microorganisms, allowing them to scavenge for scarce nutrients and survive in harsh environments.
