Melanosome formation in the goldfish: the role of multivesicular bodies.
Melanosome formation in differentiating melanophores of embryonic and adult xanthic goldfish was studied by cytochemical methods at the ultrastructural level. Large vesicles (0.4–0.5 μ m) are blebbedExpand

The carboxylation of phosphoenolpyruvate and pyruvate. I. The active species of "CO2" utilized by phosphoenolpyruvate carboxykinase, carboxytransphosphorylase, and pyruvate carboxylase.
Abstract Previous studies with propionyl coenzyme A carboxylase and with phosphoenolpyruvate carboxylase using 18O-labeled bicarbonate have indicated that bicarbonate is the reactive species in theseExpand

Regulation of pigment organelle translocation. II. Participation of a cAMP-dependent protein kinase.
In intact goldfish xanthophores, the phosphorylation of a pigment organelle (carotenoid droplet) protein, p57, appears to play an important role in adrenocorticotropin (ACTH)- or cAMP-induced pigmentExpand

Leucophores and iridophores of Fundulus heteroclitus: Biophysical and ultrastructural properties
Classical light microscopic studies on pigmentation of Fundulus heteroclitus (killifish) indicated that there are three groups of light reflecting cells; one group on the surface of scales reflectsExpand

Succinic semialdehyde dehydrogenase from a Pseudomonas species. I. Purification and chemical properties.
Abstract An NAD-specific succinic semialdehyde dehydrogenase from a Pseudomonas species has been purified. The enzyme has been shown to have low activity toward aminoaldehydes (3-aminopropanal orExpand

Purification and properties of 4-aminobutanal dehydrogenase from a Pseudomonas species.
Abstract 4-Aminobutanal dehydrogenase has been purified from a Pseudomonas species. The enzyme has high activity toward aminoaldehydes (4-aminobutanal or 3-aminopropanal) and low activity towardExpand
