Phenotypes of a mutant
cells are bent and distended due to the lack of glucolipids [Pubmed|22362028,27684739]increased expression of the [protein|search|SigM], [protein|search|SigV], and [protein|search|SigX] regulons [Pubmed|22362028]altered [SW|localization] of [protein|search|MreB] (irregular clusters instead of helical dots) [Pubmed|22362028]the inactivation of ''[protein|search|ugtP]'' suppresses the poor and filamentous growth of the ''[protein|search|yvcL] [protein|search|zapA]'' double mutant [Pubmed|24097947]increased conjugation of ICEBs1 [Pubmed|25069588]The protein
Catalyzed reaction/ biological activity
UDP-glucose 1,2-diacylglycerol = UDP 1,2-diacyl-3-(O-beta-D-glucopyranosyl)-sn-glycerol (according to Swiss-Prot)the interaction with [protein|search|FtsZ] results in inhibition of [SW|cell division] and an increase of cell size [Pubmed|22931116] Effectors of protein activity
oligomerization of [protein|search|UgtP] is inhibited by UDP-Glc and by interaction with [protein|search|FtsZ] [Pubmed|22931116][SW|Localization]
membrane-bound protein, self-assembles into tightly wound spirals ''in vitro'' [Pubmed|17662947]under nutrient rich conditions (increased concentration of UDP-Glc): throughout the cell, concentrated at the cell poles and/or the cytokinetic ring, interaction with [protein|search|FtsZ] [Pubmed|22931116]under nutrient poor conditions: forms punctate foci (oligomers), no interaction with [protein|search|FtsZ] [Pubmed|22931116][SW|Interactions]
