CommentThis HMM identifies a cluster of ABC transporter periplasmic substrate binding proteins, apparently specific for taurine. Transport systems for taurine (NH2-CH2-CH2-SO3H), sulfonates, and sulfate esters import sulfur when sulfate levels are low. The most closely related proteins outside this family are putative aliphatic sulfonate binding proteins (TIGR01728).
