Escherichia coli K-12 substr. MG1655 Polypeptide: P-loop NTPase family protein

Gene: mrp Accession Numbers: EG10611 (EcoCyc), b2113, ECK2106

Synonyms: apbC

Regulation Summary Diagram: ?

Regulation summary diagram for mrp

Mrp is a member of the Mrp/Nbp35 subfamily of the P-loop NTPases [Leipe02].

The Salmonella typhimurium ortholog, ApbC, is an ATPase that is able to bind and transfer iron-sulfur clusters [Skovran03, Boyd08, Boyd09]. Its originally proposed role in thiamine biosynthesis [Petersen96] is likely indirect.

Mrp: "metG-related protein" [Dardel90] (Note: mrp is not related to metG other than by proximity in the genome)

Review: [Roche13]

Citations: [Dardel91, High96, Gerard98]

Locations: cytosol

Map Position: [2,191,081 <- 2,192,190] (47.22 centisomes, 170°)
Length: 1110 bp / 369 aa

Molecular Weight of Polypeptide: 39.938 kD (from nucleotide sequence), 39.0 kD (experimental) [Dardel90 ]
