|Gene:||ALG7||Accession Number: G-5522 (MetaCyc)|
Synonyms: TUR1, UDP-N-acetylglucosamine: dolichyl phosphate, N-acetylglucosamine-1-phosphate transferase, UDP-N-acetylglucosamine-1-P transferase, UDP-N-acetylglucosamine-dolichyl-phosphate N-acetylglucosaminephosphotransferase, UDP-N-acetyl-D-glucosamine:dolichyl-phosphate N-acetyl-D-glucosaminephosphotransferase, N-acetyl glucosaminyl phosphate transferase
Species: Saccharomyces cerevisiae
The enzyme contains a 13-amino acid consensus sequence thought to be involved in dolichol recognition. This sequence is also found in the glycosyltransferase products of genes ALG1 and DPM1, and the product of gene SEC59 [Albright89].
The ALG7 gene is essential for cell growth [Kukuruzinska87]
