In Free Radicals, Metal Ions and Biopolymers (eds. P.C. Neaumont, D.J. Deeble, B.J. Parsons and C. Rice-Evans) pp. 329-346. RicheUeu Press, London. [Pg.94]

To test the above hypothesis, Reusch et al.30 analyzed the human erythrocyte Ca2+-ATPase pump for polyP and PHB. This protein is the first plasma membrane enzyme demonstrated to work as a Ca2+ pump, and it is the sole transporter of Ca2+ in the cell.121,122 Moreover, the Ca2+-ATPase is ubiquitous in plasma membranes of a variety of cell types in eukaryotic organisms.123... [Pg.83]

Carboxypeptidase P (EC 3.4.17.- prolylcarboxypeptidase angiotensinase C) is not fully characterized, and may be a metalloproteinase. Notable substrates of this plasma membrane enzyme include enterostatin. Inhibitors include EDTA and o-phenanthroline. [Pg.66]

In rat liver plasma membranes enzymic hydrolysis of NAD leads to free ADPR that reacts rapidly and with preference with several pcdypeptides. The pattern obtained with NAD and ADPR is practically identical. However, membrane-bound adenylate cyclase activity, which is subject to stimulation by cholera toxin [17], is not significantly influenced by nonenz3miic ADP-ribosylation of the membrane preparation. [Pg.520]

My discussion is concerned mainly with the transverse asymmetry in the distribution of plasma membrane enzymes. The scheme shown below indicates an inside-outside distribution pattern which is based on observations from several different laboratories. [Pg.163]

What follows is a brief discussion of the distribution and properties of the best characterized plasma membrane enzymes. [Pg.164]

I have also reviewed briefly the asymmetric composition of the lipid bi-layer portion of the membrane. It seems that most of the plasma membrane enzymes either contain lipid moieties or require the presence of lipids for activity. Conversely, the organization of the lipid bi-layer in the membrane may depend on these proteins. Organization requires information and I suggest that we adopt the term collocation for the information transfer which directs the organization of the lipid phase in the membrane. In this review... [Pg.169]

The plasma membrane contains an enzyme that catalyzes the export of Ca + from the cytoplasm at the expense of ATP hydrolysis. The Ca +-ATPase has features that place it in the category of plasma membrane enzymes that also includes the Na+/K+-ATPase and the H+-ATPase. The Ca +-ATPase functions to keep the cytosolic Ca +concentration low (< 1 fiM). It is not a major contributor to the generation of the membrane potential or to the energetics of the transport of bioorganic molecules. [Pg.17]

Sialidase activities directed toward ganglioside substrates in plasma membrane and lysosomal fractions can be distinguished based on their responses to detergents and inhibitors. The requirement of detergents significantly differs between both enzyme activities (see Section 5.1). Heparin or heparin sulfate almost completely inhibits the GM3 sialidase activity in the plasma membrane preparation, but only slightly affects the lysosomal enzyme activity. The inhibition of the plasma membrane enzyme, but not the lysosomal enzyme, can be... [Pg.288]

Recently, a specific antibody against the purified cytosolic sialidase from rat skeletal muscle was prepared and its immunoreactivity with other sialidases examined (Miyagi et al., 1990b). The antibody completely immunoprecipitates the cytosolic enzyme in rat liver and skeletal muscle, but not the synaptosomal and lysosomal enzymes in rat brain and liver. These results suggest that a single cytosolic sialidase species may exist in rat tissues which is immunologically distinct from the lysosomal and plasma membrane enzymes. [Pg.290]
