Peptidylglycine alpha-amidating monooxygenase (PAM) catalyzes the COOH-terminal amidation of bioactive peptides through a two step reaction catalyzed by separate enzymes contained within the PAM precursor. To characterize the trafficking of integral membrane PAM proteins in neuroendocrine cells, we have generated stable AtT-20 cell lines expressing full length and COOH-terminally truncated inte...

<p>The objective of this work is to simulate a pulse amplitude modulation (PAM) scheme based on in-line semiconductor optical amplifiers for soliton systems. The max. power systems, various bits/symbol PAM schemes after fiber length 100 km, simulated and clarified. In addition the Q factor with SOA injection currents km are also demonstrated in results. total electrical photo-detectors cl...

BACKGROUND Antenatal intermittent preventive therapy with 2 doses of sulfadoxine-pyrimethamine (IPTp-SP) is the mainstay of efforts in sub-Saharan Africa to prevent pregnancy-associated malaria (PAM). Recent studies report that drug resistance may cause IPTp-SP to exacerbate PAM morbidity, raising fears that current policies will cause harm as resistance spreads. METHODS We conducted a serial...

Peptidylglycine alpha-amidating monooxygenase (PAM) catalyzes the COOH-terminal alpha-amidation of neuro-endocrine peptides through the sequential action of monooxygenase and lyase domains contained within this bifunctional protein. Alternative splicing leads to the expression of soluble and integral membrane bifunctional PAM proteins as well as a soluble monofunctional monooxygenase. In order ...

Peptidylglycine alpha-amidating monooxygenase (PAM), a bifunctional enzyme, catalyzes the COOH-terminal amidation of bioactive peptides. In test tube assays, PAM is phosphorylated by protein kinase C at Ser(937). The roles of phosphorylation and dephosphorylation of Ser(937) in the biosynthetic and endocytic trafficking of integral membrane PAM were examined using an antiserum specific for the ...

Waste streams associated with a variety of agricultural runoff sources are major contributors of nutrients, pesticides and enteric microorganisms to surface and ground waters. Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1-10 g m(-3) in furrow irrigation water. Water flowing from PAM...

PURPOSE To evaluate clinical features and risks for transformation of conjunctival primary acquired melanosis (PAM) into melanoma. METHODS Retrospective chart review and Kaplan-Meier estimates of times to PAM enlargement, recurrence, and transformation into melanoma. MAIN OUTCOME MEASURES PAM enlargement, recurrence, and transformation into melanoma. RESULTS The mean patient age at diagno...
