Gene

Organism
Lactococcus lactis subsp. lactis (strain IL1403) (Streptococcus lactis)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the condensation of ATP and 5-phosphoribose 1-diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity.

Catalytic activityi

1-(5-phospho-beta-D-ribosyl)-ATP + diphosphate = ATP + 5-phospho-alpha-D-ribose 1-diphosphate.

Pathwayi: L-histidine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate.
Proteins known to be involved in the 9 steps of the subpathway in this organism are:
  1. ATP phosphoribosyltransferase (hisG), ATP phosphoribosyltransferase regulatory subunit (hisZ)
  2. Histidine biosynthesis bifunctional protein HisIE (hisI)
  3. Histidine biosynthesis bifunctional protein HisIE (hisI)
  4. 1-(5-phosphoribosyl)-5-[(5-phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase (hisA)
  5. Imidazole glycerol phosphate synthase subunit HisH (hisH), Imidazole glycerol phosphate synthase subunit HisF (hisF)
  6. Imidazoleglycerol-phosphate dehydratase (hisB)
  7. Histidinol-phosphate aminotransferase (hisC)
  8. Histidinol-phosphatase (hisK)
  9. Histidinol dehydrogenase (hisD)
This subpathway is part of the pathway L-histidine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate, the pathway L-histidine biosynthesis and in Amino-acid biosynthesis.

The stability and homogeneity of the HisG-HisZ complex is apparently increased by ATP and 5-phosphoribose 1-diphosphate but decreased in the presence of the regulatory inhibitor histidine.
