Porphyrin Metabolism and Disorders

The endoplasmic reticulum (ER), comprises 60% of the total cell membrane and interacts directly or indirectly with several cell organelles i.e., Golgi bodies, mitochondria and proteasomes. The ER is usually associated with large numbers of attached ribosomes. During evolution, ER developed as the specific cellular sit…

The kinetics of excision of damaged purine bases from oxidatively damaged DNA by Escherichia coli Fpg protein were investigated. DNA substrates, prepared by treatment with H2O2/Fe(III)-EDTA or by gamma-irradiation under N2O or air, were incubated with Fpg protein, followed by precipitation of DNA. Precipitated DNA and…

Xeroderma pigmentosum group C (XP-C) is a rare autosomal recessive disorder. Patients with two mutant alleles of the XPC DNA repair gene have sun sensitivity and a 1000-fold increase in skin cancers. Clinically normal parents of XP-C patients have one mutant allele and one normal allele. As a step toward evaluating ca…

Figures of eight correlate with corrolates: The surprising formation of the spirodicorrole dinickel complex 1, the first spirodiporphyrin as a metal complex, is the result of the varied chemistry of the “figure-eight” cyclooctapyrrole octaphyrin-(1.1.1.0.1.1.1.0). The conversion of the cyclooctapyrrole into 1 is broug…

Selective intestinal malabsorption of vitamin B(12) causing juvenile megaloblastic anemia (MGA; MIM# 261100) is a recessively inherited disorder that is believed to be rare except for notable clusters of cases in Finland, Norway, and the Eastern Mediterranean region. The disease can be caused by mutations in either th…
