Studies on the enzymes involved in puparial cuticle sclerotization in Drosophila melanogaster.
Sugumaran M, Giglio L, Kundzicz H, Saul S, Semensi V. Sugumaran M, et al. Arch Insect Biochem Physiol. 1992;19(4):271-83. doi: 10.1002/arch.940190406. Arch Insect Biochem Physiol. 1992. PMID: 1600191
Our results indicate that this catecholamine derivative is biosynthesized from N-acetyldopamine through the intermediate formation of N-acetyldopamine quinone and N-acetyldopamine quinone methide as established for Sarcophaga bullata [Saul, S. and Sugumaran, M., F.E …

Complex formation between mushroom tyrosinase and Manduca dopachrome isomerase.
Sugumaran M, Nellaiappan K, Scott T, Amaratunga C. Sugumaran M, et al. Pigment Cell Res. 1995 Aug;8(4):180-6. doi: 10.1111/j.1600-0749.1995.tb00661.x. Pigment Cell Res. 1995. PMID: 8610068
We have characterized a novel dopachrome isomerase (decarboxylating) from the hemolymph of Manduca sexta that generates a new quinone methide intermediate during melanogenesis (Sugumaran, M. and Semensi, V. (1991) J. Biol. Chem. 266, 6073-6078). ...

Insect melanogenesis. III. Metabolon formation in the melanogenic pathway-regulation of phenoloxidase activityy by endogenous dopachrome isomerase (decarboxylating) from Manduca sexta.
Sugumaran M, Nellaiappan K, Amaratunga C, Cardinale S, Scott T. Sugumaran M, et al. Arch Biochem Biophys. 2000 Jun 15;378(2):393-403. doi: 10.1006/abbi.2000.1848. Arch Biochem Biophys. 2000. PMID: 10860557
Earlier, we reported the partial purification of dopachrome isomerase (decarboxylating) from the hemolymph of Manduca sexta and demonstrated the generation of a new quinone methide intermediate during melanogenesis (Sugumaran, M., and Semensi, V. (1991) J. Biol. Che …
