R257 (= R251) mutation to C: Sodium-independent binding affinity for proline.
C281 (≠ S275) 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 (≠ S334) mutation to S: Small decrease in proline uptake activity. Confers resistance to N-ethylmaleimide. Exhibits low Na(+)-dependent proline binding.
C349 (≠ S339) 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 (= R366) mutation R->E,Q: No change in activity.; mutation to K: Loss of activity.

P11170 Sodium/glucose cotransporter 1; Na(+)/glucose cotransporter 1; High affinity sodium-glucose cotransporter; Solute carrier family 5 member 1 from Oryctolagus cuniculus (Rabbit) (see 2 papers)
23% identity, 70% coverage: 92:427/481 of query aligns to 126:492/662 of P11170
