Regulation summary diagram for gutQ

Subunit composition of D-arabinose 5-phosphate isomerase = [GutQ]4
         D-arabinose 5-phosphate isomerase = GutQ

gutQ encodes the second of two D-arabinose 5-phosphate isomerases (API) in E. coli. Its biochemical properties are very similar to those of KdsD, the first identified D-arabinose 5-phosphate isomerase. Strains containing single mutations in either the kdsD or gutQ genes are viable and have a functional LPS. A kdsD gutQ double mutant strain required the addition of exogenous arabinose 5-phosphate for viability [Meredith & Woodard, 2005].

GutQ has previously been shown to have a sugar isomerase (SIS) domain [Bateman, 1999] and a predicted ATP binding site [Yamada et al., 1990]. GutQ also has similarity to of E. coli K1 KpsF, which plays a role in polysialic acid capsule expression [Cieslewicz & Vimr, 1997].

gutQ is the last gene in the gut operon, and its expression is induced by glucitol [Yamada et al., 1990, Meredith & Woodard, 2005]. GutQ appears to be involved in biofilm formation. A mutant with a deletion of gutQ shows a significant decrease in biofilm formation. Expression of gutQ increases 9-fold upon deletion of tqsA, which increases biofilm formation [Herzberg et al., 2006].
