Escherichia coli K-12 substr. MG1655 Polypeptide: predicted inner membrane protein



Gene: yicL Accession Numbers: EG11688 (EcoCyc), b3660, ECK3650

Regulation Summary Diagram: ?

Summary:
YicL is an inner membrane protein with ten predicted transmembrane domains. The C terminus is located in the cytoplasm [Daley05].

Overexpression of YicL or the ORF296 protein from Glycine max (soybean) inhibits growth of E. coli and leads to slightly increased accumulation of δ-aminolevulinic acid (ALA). The authors proposed that YicL may inhibit the biosynthesis of heme, possibly by inhibiting HemB [Kanjo01].

Locations: inner membrane

Map Position: [3,836,271 -> 3,837,194] (82.68 centisomes)
Length: 924 bp / 307 aa

Molecular Weight of Polypeptide: 33.112 kD (from nucleotide sequence)
