Escherichia coli K-12 substr. MG1655 Polypeptide: glucan biosynthesis protein D



Gene: opgD Accession Numbers: EG12859 (EcoCyc), b1424, ECK1418

Synonyms: yzzZ, ydcG, mdoD

Regulation Summary Diagram: ?

Summary:
The opgD gene was identified in silico as a paralog of opgG [Lequette04]. The protein was thought to be secreted to the periplasmic space via the twin-arginine translocation (Tat) pathway, but a tatC mutation does not affect its localization to the periplasmic space. OpgD thus can be exported by both the Tat and Sec pathways [TullmanErcek07].

A mutation in opgD does not cause gross changes in the synthesis or function of osmoregulated periplasmic glucans (OPGs), but alters the size of the glucose backbone of OPG molecules [Lequette04].

opgD: osmoregulated periplasmic glucan [Lequette04]
mdoD: membrane derived oligosaccharide

Locations: periplasmic space

Map Position: [1,494,880 -> 1,496,535] (32.22 centisomes)
Length: 1656 bp / 551 aa

Molecular Weight of Polypeptide: 62.758 kD (from nucleotide sequence)
