Melanosome formation in the goldfish: the role of multivesicular bodies.
- W. A. Turner, J. Taylor, T. Tchen
- Biology, Medicine
- Journal of ultrastructure research
- 1 April 1975
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 blebbed… Expand
The carboxylation of phosphoenolpyruvate and pyruvate. I. The active species of "CO2" utilized by phosphoenolpyruvate carboxykinase, carboxytransphosphorylase, and pyruvate carboxylase.

- Biology, Medicine
- The Journal of biological chemistry
- 25 July 1968
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 these… Expand

- Biology, Medicine
- The Journal of biological chemistry
- 25 March 1986
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 pigment… Expand
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 reflects… Expand
Succinic semialdehyde dehydrogenase from a Pseudomonas species. I. Purification and chemical properties.
- D. Callewaert, M. Rosemblatt, K. Suzuki, T. Tchen
- Biology, Medicine
- The Journal of biological chemistry
- 10 September 1973
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 or… Expand
