R257 (= R286) mutation to C: Sodium-independent binding affinity for proline.
C281 (≠ T314) mutation to S: Does not affect proline uptake activity. Confers resistance to N-ethylmaleimide. Na(+)-dependent proline binding activity is similar to wild-type carrier.
C344 (≠ G376) mutation to S: Small decrease in proline uptake activity. Confers resistance to N-ethylmaleimide. Exhibits low Na(+)-dependent proline binding.
C349 (≠ G381) mutation to S: Does not affect proline uptake activity. Sensitive to N-ethylmaleimide. Na(+)-dependent proline binding activity is similar to wild-type carrier.
R376 (≠ K409) mutation R->E,Q: No change in activity.; mutation to K: Loss of activity.
