Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Summary: The protein encoded by this gene shares 22% sequence identity with Hemophilus influenzae xylulokinase, and even higher identity to other gene products in C.elegans (45%) and yeast (31-35%), which are thought to belong to a family of enzymes that include fucokinase, gluconokinase, glycerokinase and xylulokinase. These proteins play important roles in energy metabolism. [provided by RefSeq, Aug 2009]

What's a GeneRIF?

Single nucleotide polymorphisms in nNOS, renalase, MTHFR, CELSR1 and XYLB genes were found significantly associated with ischemic stroke in Chinese patients.
Title: Pooled genetic analysis reveals an association of SNPs of only a few genes with risk predisposition to ischemic stroke in a Chinese population.
Xylulose binds to domain-I and ADP to domain-II, but in an open form of D-xylulokinase they are 10 A apart, implying that a large scale conformational change is required for catalysis.
Title: Structure and function of human xylulokinase, an enzyme with important roles in carbohydrate metabolism.
crystals of D-xylulokinase proved to be trigonal, with point-group symmetry 3 and unit-cell parameters a = b = 101.87, c = 158.85 A degrees

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
