MetS family NSS transporter small subunit MetS, as described in the Gram-positive bacterium Corynebacterium glutamicum, is the small subunit of MetPS, an NSS (Neurotransmitter:Sodium Symporter) transporter involved in methionine and alanine import. While MetS itself is small, only 60 amino acids, homologs in gamma proteobacteria such as Vibrio sp., similarly found next to an NSS transporter large subunit, may be barely half that length and consist almost entirely of a predicted hydrophobic region that would localize to within the plasma membrane. |
