'A novel aminopeptidase with unique substrate specificity was purified from a culture broth of Sphingomonas capsulata. This is the first reported aminopeptidase to demonstrate broad substrate specificity and yet release glycine and alanine with the highest efficacy. On a series of pentapeptide amides with different N-terminal amino acids, this enzyme ... More
cAMP-dependent phosphorylation of two sites in the alpha subunit of the cardiac sodium channel.
'The voltage-sensitive Na+ channel is responsible for generating action potentials in the heart which are critical for coordinated cardiac muscle contraction. Cardiac Na+ channels are regulated by cAMP-dependent phosphorylation, but the sites of phosphorylation are not known. Using mammalian cells expressing the rat cardiac Na+ channel (rH1) alpha subunit and ... More
Molecular characterization and developmental expression of a retinoid- and fatty acid-binding glycoprotein from Drosophila. A putative lipophorin.
A detailed understanding of the mechanism of lipid transport in insects has been hampered by the inability to identify the proapolipophorin gene that encodes apolipophorins I and II, the principal protein components of lipophorin, the lipid transport vehicle. Here we provide the first molecular description of the Drosophila gene encoding ... More
