2.A.56.2.1
TRAP transporter for a hydrophobic substrate (3-d structure known; tp0958 has 18-20 TMSs) (Deka et al., 2012). The substrate could be a lipoprotein, tp0956 (O83922) which is encoded in the same operon with tp0957 and tp058. This protein differs from all other members of the TRAP-T family in having 19 predicted TMSs with extra TMSs at its N-terminus.

Accession Number:O83923
Protein Name:Tp33 protein
Length:342
Molecular Weight:38312.00
Species:Treponema pallidum (strain Nichols) [243276]
Number of TMSs:4
Substrate ectoine, 5-hydroxyectoine
