P07117 Sodium/proline symporter; Proline carrier; Proline permease; Propionate transporter from Escherichia coli (strain K12) (see 4 papers)
26% identity, 77% coverage: 58:484/554 of query aligns to 25:448/502 of P07117
- R257 (= R288) mutation to C: Sodium-independent binding affinity for proline.
- C281 (≠ A316) 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 (≠ G378) mutation to S: Small decrease in proline uptake activity. Confers resistance to N-ethylmaleimide. Exhibits low Na(+)-dependent proline binding.
- C349 (≠ G383) 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 (= R411) mutation R->E,Q: No change in activity.; mutation to K: Loss of activity.
Q92911 Sodium/iodide cotransporter; Na(+)/I(-) cotransporter; Natrium iodide transporter; Sodium-iodide symporter; Na(+)/I(-) symporter; Solute carrier family 5 member 5 from Homo sapiens (Human) (see 3 papers)
26% identity, 33% coverage: 43:223/554 of query aligns to 19:201/643 of Q92911
- A102 (≠ L123) natural variant: A -> P
Sites not aligning to the query:
- 226 mutation H->A,D,E,K: Significant loss of iodide transport activity but no effect on its localization to the cell membrane.
- 237 D→A: Loss of localization to the cell membrane, significant loss of iodide transport activity but no effect on homodimerization.
- 242 Required for homodimerization; Y→A: Loss of localization to the cell membrane, significant loss of iodide transport activity but no effect on homodimerization. Reduced homodimerization; when associated with A-471. Loss of iodide transport activity; when associated with F-535.
- 243 Required for homodimerization; T→A: Loss of localization to the cell membrane, significant loss of iodide transport activity but no effect on homodimerization. Reduced homodimerization; when associated with A-471.
- 471 Required for homodimerization; Q→A: No effect on localization to the cell membrane, iodide transport activity and homodimerization. Significant loss of homodimerization; when associated with A-242 or A243.
- 525 A→F: Loss of localization to the cell membrane, significant loss of iodide transport activity but no effect on homodimerization. Loss of iodide transport activity; when associated with A-242.
- 536 T → Q: requires 2 nucleotide substitutions
- 556 S → Q: requires 2 nucleotide substitutions
5nv9A Substrate-bound outward-open state of a na+-coupled sialic acid symporter reveals a novel na+-site (see paper)
27% identity, 31% coverage: 59:227/554 of query aligns to 25:192/480 of 5nv9A
- binding sodium ion: A52 (≠ G86), T53 (≠ D87), L55 (≠ M89), S56 (= S90), V174 (≠ T209), D178 (≠ Q213)
- binding N-acetyl-beta-neuraminic acid: T54 (≠ F88), S56 (= S90), I58 (≠ A92), T59 (≠ S93), G77 (= G108), Q78 (≠ M109), R131 (vs. gap)
Sites not aligning to the query:
Q9NY91 Probable glucose sensor protein SLC5A4; Solute carrier family 5 member 4 from Homo sapiens (Human) (see paper)
26% identity, 22% coverage: 134:257/554 of query aligns to 124:252/659 of Q9NY91
Sites not aligning to the query:
- 457 E→Q: Confers sugar transport activity not found in the wild-type protein. Increased sensitivity to inhibitor phlorizin.
