Example sentences for: phosphatases

How can you use “phosphatases” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • First, PfPP5 contained the catalytic core found in all Ser/Thr phosphatases of the PPP family, including the signature motifs such as GDXHGQ, GDFVDRG, RGNHE, HGLL, and SAPNYCD, to name a few [ 22 23 ] . Site-directed mutagenesis and structural studies in PP 1 and PPλ have previously established the roles of specific amino acid residues in these domains in the various aspects of catalysis, such as metal ion binding, phosphate recognition, and co-ordination of water molecules [ 24 25 26 ] .

  • To identify new Ser/Thr phosphatases of Pf, we have recently undertaken a PCR-based approach.

  • Other families, such as the phosphatases, Rbohs and CBL/SOS3S, also contribute to the complexity of Ca 2+involvement in the regulation of many processes.

  • One of the major cellular serine/threonine protein phosphatases is protein phosphatase type 1 (PP1) [ 1 ] . An abundant enzyme expressed in all cells, complex regulation of PP1 is thought to be essential for proper temporal and spatial regulation of PP1 catalytic activity towards individual substrates [ 2 ] . Three different isotypes of the catalytic subunit, designated PP1α, PP1δ, and PP1γ1, are expressed in many different cell types [ 3 ] . Studies employing many eukaryotic systems all point to a crucial role for PP1 activity in controlling cell cycle progression, and an absolute requirement of this activity for mitotic exit [ 4 5 6 7 ] . There is also evidence to suggest that phosphorylation of PP1 and its associated proteins by the cyclin-dependent kinases may regulate PP1 activity in a cell cycle stage-dependent manner [ 8 9 10 ] . Hence, current efforts are directed towards identification of cell cycle-dependent substrates for PP1, and how regulation of PP1 activity towards these substrates controls the cell division cycle.

  • Other enzymes, such as deacetylases and phosphatases, remove covalent modifications from proteins and thus reverse their effects [ 4, 5, 6].
