Magnetic properties of an analog compound for cytochrome P-450

Creator:: McCann, Steven Wayne
Abstract:: This thesis describes a Mossbauer effect and electron paramagnetic resonance study of iron (III) tetraphenylporphyrinatobenzenethiolate benzene thiol, an analog compound for bacterial cytochrome P-450. The compound is unusual in that it provides a model for the two ferric reaction states of cytochrome P-450. The iron in the model compound exhibits...

Biosynthesis of blasticidin S : mechanistic and stereochemical investigations

Creator:: Prabhakaran, P. C.
Abstract:: Feeding of [3-¹³C, 2-¹⁵N]arginine, 38a, unequivocally established that the β- arginine moiety of blasticidin S, 1, was formed from α-arginine by an intramolecular migration of the α-amino group to the β- position. Further feedings using chirally deuteriated arginines 38e and 38f revealed that the aminomutase process occurred with inversion of...

Purification of 2,5-dihydroxyacetanilide epoxidase and mechanism of hydroquinone epoxidases

Creator:: Kirchmeier, Marc J.
Abstract:: 2,5-dihydroxyacetanilide epoxidase from Streptomyces LL-C10037 (DHAE I) catalyzes the epoxidation of hydroquinone 4, to form epoxyquinone 7. DHAE I has been purified to homogeneity, with an overall purification factor greater than 23,000. N-terminal and internal amino acid sequences have been obtained from the purified enzyme so that the epoxidase gene...

Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

Metabolism of L-α-arginine in the biosynthesis of blasticidin S

Creator:: Woo, Nam-tae
Abstract:: Two labelled arginines, DL-[2,3,3,-²H₃]arginine, 8, and DL-[ ¹³C, 2-¹⁵N]arginine, 9, were synthesized. These were fed to cultures of Streptomyces griseochromogenes in order to probe the mechanism of the apparent arginine-2,3- aminomutase reaction occurring in biosynthesis of blasticidin S, 1. In previous studies of the enzymes lysine-2,3- aminomutase and tyrosine-2,3-aminomutase different...
