Words similar to bifunctional
Example sentences for: bifunctional
How can you use “bifunctional” in a sentence? Here are some example sentences to help you improve your vocabulary:
GSPS is a bifunctional enzyme: its synthase domain carries out the ATP-dependent fusion of two glutathione moieties to the polyamine spermidine to form the antioxidant metabolite GSP, while its amidase domain hydrolyzes the amide linkage to release glutathione and spermidine [ 26, 55, 56].
Examples are the bifunctional proteins ThrA (aspartokinase I and homoserine dehydrogenase I) and MetL (aspartokinase II and homoserine dehydrogenase II) where only the amino-terminal modules representing the kinase activities have been identified on the basis of their sequence similarity to the E. coli unimodular aspartokinase III (LysC).
In C. elegans , two genes each encode unusual bifunctional enzymes containing both isocitrate lyase and malate synthase domains [ 49 ] . Since the isocitrate lyase domain lies within the amino-terminal half of the C. elegans bifunctional enzyme and none of the Meloidogyne EST reads stretches across both domains, further sequencing of the 3' end of cDNA clones from the M. hapla or M. javanica isocitrate lyase ESTs will be necessary to determine whether the Meloidogyne genus contains a bifunctional glyoxylate enzyme homolog similar to that of
These same organisms also possess AroQ•PheA bifunctional proteins whose AroQ domains also form a cohesive homology grouping.
Although the three capping reactions are universal in eukaryotes, there is a surprising diversity in the genetic organization of the capping enzymes as well as a complete divergence in the structure and catalytic mechanism of the RNA triphosphatase component in "lower" versus "higher" eukaryotic species [ 1 ] . Metazoans and plants have a two-component capping system consisting of a bifunctional triphosphatase-guanylyltransferase polypeptide and a separate methyltransferase polypeptide, whereas fungi contain a three-component system consisting of separate triphosphatase, guanylyltransferase, and methyltransferase gene products.
