Description:
Modification of cell surface molecules with sialic acid is crucial for their function in many biological processes, including cell adhesion and signal transduction. Uridine diphosphate-N-acetylglucosamine 2-epimerase (UDP-GlcNAc 2-epimerase) is an enzyme that catalyzes an early, rate-limiting step in the sialic acid biosynthetic pathway. UDP-GlcNAc 2-epimerase was found to be a major determinant of cell surface sialylation in human hematopoietic cell lines and a critical regulator of the function of specific cell surface adhesion molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keppler, O T -- Hinderlich, S -- Langner, J -- Schwartz-Albiez, R -- Reutter, W -- Pawlita, M -- New York, N.Y. -- Science. 1999 May 21;284(5418):1372-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Applied Tumor Virology Program, Tumor Immunology Program, Deutsches Krebsforschungszentrum, Im Neuenheimer Feld 280, D-69120 Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10334995" target="_blank"〉PubMed〈/a〉
