2.A.32.1.1 | Silicon transporter of 548 aas and 10 probable TMSs in a 2 + 3 + 2 + 3 TMS arrangement. It has a conserved aa motif, CMLD. Hydropathy profiles suggest that CMLD occupies a position between two TMSs. These two TMSs are candidates for a role of the channel through which transport of silicic acid occurs (Shcherbakova et al. 2006). | Eukaryota |
Bacillariophyta | Sit1 of Cylindrotheca fusiformis (marine diatom) |
|
2.A.32.1.2 | Silicon transporter, SIT1, of 546 aas and 10 probable TMSs in a 2 + 3 + 2 + 3 TMS arrangement. | Eukaryota |
Bacillariophyta | SIT1 of Nitzschia alba (marine diatom) |
|
2.A.32.1.3 | Silicic acid transport protein, SIT, of 571 aas and 12 or 13 TMSs in a possible 1 + 2 + 3 + 2 + 3 +2 TMS arrangement. | Eukaryota |
Bacillariophyta | SIT of Ulnaria acus |
|
2.A.32.1.4 | Silicic acid transporter, Sit1, of 503 aas and 10 TMSs in a 2 + 3 + 2 + 3 TMS arrangement (Durak et al. 2016). | Eukaryota |

2.A.32.1.6 | Putative silicon transporter of 225 aas, Sit, with proably 5 or 6 TMSs in a 2 + 3 or 2 + 3 + 1 TMS arrangement. This sequence (which could be a fragment) shows about the same percent identity with both halves of the longer proteins listed in TC#s 2.A.32.1.1 - 1.5. | Eukaryota |
Bacillariophyta | Sit of Fragilaria crotonensis |
|
2.A.32.1.7 | Silicon transporter, Sit, of 477 aas and 10 TMSs in a 2 + 3 + 2 + 3 TMS arrangement. | Eukaryota |

|
2.A.32.1.8 | Uncharacterized protein of 407 aas with 5 TMSs in a 2 + 3 TMS arrangement (residues 1 - 210) followed by a 200 residue hydrophilic domain. Residues 1 - 210 show about equal sequence similarity with the two halves of all of the full length sequences (2.A.32.1.1 - 1.5 and 1.7). The N-terminal half of the protein seems to be a half transporter and may function as a dimer in the membrane. | Eukaryota |

|
2.A.32.1.10 | Uncharacterized half transporter of 361 aas with 5 TMSs in a 2 + 3 TMS arrangement followed by a hydrophilic domain similar in sequence to those for 2.A.32.1.8 and 9. | Eukaryota |
