Disease relevance of xylB

Structural and Kinetic Studies of Induced Fit in Xylulose Kinase from Escherichia coli [1].

High impact information on xylB

Xylulose kinase (XK; EC 2.7.1.17) phosphorylates d-xylulose, the last step in this conversion [1].
A cytosolic Arabidopsis d-xylulose kinase catalyzes the phosphorylation of 1-deoxy-d-xylulose into a precursor of the plastidial isoprenoid pathway [2].
It was identified by mass spectrometry as a cytosolic protein bearing d-xylulose kinase (XK) signatures, already suggesting that DX is phosphorylated within the cytosol prior to translocation into the plastids [2].

Biological context of xylB

The gene encoding the plastidic protein annotated as "xylulose kinase" might in fact yield an enzyme having different phosphorylation specificities [2].
