P07117 Sodium/proline symporter; Proline carrier; Proline permease; Propionate transporter from Escherichia coli (strain K12) (see 4 papers)
27% identity, 97% coverage: 9:478/483 of query aligns to 8:480/502 of P07117
- R257 (= R259) mutation to C: Sodium-independent binding affinity for proline.
- C281 (≠ L283) 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 (≠ A338) mutation to S: Small decrease in proline uptake activity. Confers resistance to N-ethylmaleimide. Exhibits low Na(+)-dependent proline binding.
- C349 (≠ S343) 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 (≠ A371) mutation R->E,Q: No change in activity.; mutation to K: Loss of activity.
