Phenotypes of a mutant
unable to grow with gluconeogenic substrates as single carbon source, this can be suppressed by mutations in [gene|ADA6F2EDC7B18FDFFA47CC8C55BCDDE1B6821160|cggR], [gene|43CD2581DA421CABC66E30389640CC86E6B2D800|zwf], [gene|8D0885839CD60C05FB806BBF08AFA05225E83B12|pgpH], [gene|418900B6DBDF3EF300C930B0C75E31B939F3CE00|ltaS], [gene|CCD06F344E3C87E77C3D13883CE2B927F372A84E|yfnI], upon overexpression of [gene|4E23D2043D51C587027ABBF6335F148295E90B8F|glmS] or by a point mutation in [protein|70412A747D1ED3E885126945DF02503667C13E5B|pgcA] (G47S) that results in increased phosphoglucosamine mutase activity [Pubmed|31589605,30478337,30248093,16272399]
filamentous or L-shape-like aberrant morphologies (suppressed by Mg2+) [Pubmed|16272399], this is supressed by overexpression of [protein|A4C8719E06F774A6EB4D79757CC79CF89E453A54|mreB] or by deletion of [gene|A8EEC896B279CFDDE9C3A6F146A04EC822E33A4F|PBP1], [gene|418900B6DBDF3EF300C930B0C75E31B939F3CE00|ltaS], or [gene|CCD06F344E3C87E77C3D13883CE2B927F372A84E|yfnI] [Pubmed|30478337,21320184]

The protein
Catalyzed reaction/ biological activity
GlcNAc-1P + UTP --> UDP-N-acetylglucosamine [pubmed|36939339]
stimulates [protein|4E23D2043D51C587027ABBF6335F148295E90B8F|glmS] activity to facilitate the diversion of carbon from fructose-6-phosphate to peptidoglycan synthesis [pubmed|32994436,30248093]
interacts with [protein|EB12C6B4F36B57BF0C59CE048CBAE18734C78D35|yvcJ] to facilitate genetic transformation [pubmed|32994436]
Protein family
gluconeogenesis factor family (single member, according to UniProt)
[wiki|Domains]
phosphorylated on Thr-304 by [protein|23FF4A00C36EC1B7297F51A9EF3579B41F0B7EBA|prkC], dephosphorylated by [protein|84447F9A6644EA8A7593BB99B2B69D4377E670E2|prpC] [Pubmed|25012659]
Structure
[PDB|2O2Z] (the protein from ''B. halodurans'', 63% identity, 86% similarity)
[AF|O06974]
Effectors of protein activity
binds UDP-GlcNAc [pubmed|28646159], this prevents the interaction with [protein|4E23D2043D51C587027ABBF6335F148295E90B8F|glmS] and stimulates interaction with [protein|EB12C6B4F36B57BF0C59CE048CBAE18734C78D35|yvcJ] [pubmed|32994436,30248093]
[wiki|Localization]
