• Modification:

• Cofactor(s):

• Effectors of protein activity:
  • oligomerization of UgtP is inhibited by UDP-Glc and by interaction with FtsZ PubMed

• Interactions:
  • EzrA-UgtP PubMed
  • UgtP-UgtP PubMed, forms oligomers PubMed
  • UgtP-FtsZ (under nutrient rich conditions) PubMed

• Localization:
  • membrane-bound protein, self-assembles into tightly wound spirals in vitro PubMed
  • under nutrient rich conditions (increased concentration of UDP-Glc): throughout the cell, concentrated at the cell poles and/or the cytokinetic ring, interaction with FtsZ PubMed
  • under nutrient poor conditions: forms punctate foci (oligomers), no interaction with FtsZ PubMed
