- * Sodium:alanine symporter family signature *
- *********************************************
-
- It has been shown [1] that integral membrane proteins that mediate the intake
- of a wide variety of molecules with the concomitant uptake of sodium ions
- (sodium symporters) can be grouped, on the basis of sequence and functional
- similarities into a number of distinct families. One of these families is
- known as the sodium:alanine symporter family (SAF) and currently consists of
- the following proteins:
-
- - Thermophilic bacterium PS-3 alanine carrier protein (ACP). ACP can use both
- sodium and hydrogen as a symport ion.
- - Alteromonas haloplanktis D-alanine/glycine permease (gene dagA).
- - Escherichia coli hypothetical protein yaaJ.
-
- These integral membrane proteins are predicted to comprise a least eight
- membrane spanning domains. As a signature pattern we selected a highly
- conserved region which is located in the N-terminal section and which includes
- part of the first transmembrane region.
-
- -Consensus pattern: G-G-P-[GA](2)-[LIVM]-F-W-M-W
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
