Escherichia coli K-12 substr. MG1655 Polypeptide: aliphatic sulfonate ABC transporter - membrane subunit



Gene: ssuC Accession Numbers: G6476 (EcoCyc), b0934, ECK0925

Synonyms: ycbM

Regulation Summary Diagram: ?

Component of: aliphatic sulfonate ABC transporter (extended summary available)

Summary:
Based on sequence analysis ssuC encodes the integral membrane component of an aliphatic sulfonate ABC transporter [vanDer99]. An ΔssuC ΔssuB strain is unable to grow using a range of aliphatic sulfonates as sulfur source including MOPS, HEPES, ethanesulfonate, hexanesulfonate, octanesulfonate, decanesulfonate and sulfoacetate. Wild type growth is restored when ssuC and ssuB are expressed from a plasmid [Eichhorn00].

SsuC contains 6-7 predicted transmembrane helices; the N and C-termini are located in the cytoplasm [Drew02].

Subunit of: aliphatic sulfonate ABC transporter

Synonyms: YcbE/YcbM ABC transporter, alkanesulfonate ABC transporter

Subunit composition of aliphatic sulfonate ABC transporter = [SsuA][SsuC]2[SsuB]2
         aliphatic sulfonate ABC transporter - periplasmic binding protein = SsuA (summary available)
         aliphatic sulfonate ABC transporter - membrane subunit = SsuC (summary available)
         aliphatic sulfonate ABC transporter - ATP binding subunit = SsuB (summary available)

Summary:
The ssuEADCB gene cluster codes for proteins that enable Escherichia coli to utilize a broad range of sulfonates as a source of sulfur.

A strain lacking the chromosomal ssuEADBC gene cluster is unable to use a broad range of aliphatic sulfonates as sulfur source including ethanesulfonate, propanesulfonate, butanesulfonate, pentanesulfonate, hexanesulfonate, ethanedisulfonate, octanesulfonate, decanesulfonate, isethionate, sulfoacetate, MOPS, HEPES, MES, and PIPES but is able to use sulfur from sulfate, cysteine, cystine, lanthionine, methionine, glutathione and taurine [vanDer99]. Deletion of the ssu transporter gene cluster results in the inability to use 4-phenyl-1-butanesulfonate, 2-(4-pyridyl)ethanesulfonate, 3-aminopropanesulfonate, and N-phenyltaurine as a sulfur source [Eichhorn00].

Based on sequence analysis SsuABC is an ABC type transport system with SsuA being the periplasmic substrate-binding subunit, SsuB the ATP-binding subunit, and SsuC the permease [vanDer99]. ssuD and ssuE encode an FMNH2-dependent sulfonate monooxygenase and an NAD(P)H-dependent FMN reductase, respectively.
