Urinary porphyrin excretion in hepatitis C infection [PDF]
A high prevalence of hepatitis C virus infection in porphyria cutanea tarda in some populations suggests a close link between viral hepatitis and alteration of porphyrin metabolism.

Acute intermittent porphyria: Diagnostic dilemma and treatment options
Acute intermittent porphyria (AIP) presents with diverse group of symptoms making its early diagnosis difficult. Delaying diagnosis and treatment of AIP can be fatal or can cause long term or permanent neurological damage.

Acute Intermittent Porphyria: Flaccid Quadriplegia and Encephalopathy due to Posterior Reversible Encephalopathy Syndrome (PRES) [PDF]
A deficiency of the enzyme HMB Hydroxymethylbilane synthase function, also known as porphobilinogen deaminase, leads to the emergence of acute intermittent porphyria (AIP). AIP is an uncommon form of hepatic porphyria inherited in an autosomal dominant

Enigmatic Evolutionary History of Porphobilinogen Deaminase in Eukaryotic Phototrophs
In most eukaryotic phototrophs, the entire heme synthesis is localized to the plastid, and enzymes of cyanobacterial origin dominate the pathway.

Only complete rejoining of DNA strand breaks after UVC allows K562 cell proliferation and DMSO induction of erythropoiesis [PDF]
DNA strand breaks are early intermediates of the repair of UVC-induced DNA damage, however, since they severely impair cellular activities, their presence should be limited in time.

X-ray structure of a putative reaction intermediate of 5-aminolaevulinic acid dehydratase [PDF]
The X-ray structure of yeast 5-aminolaevulinic acid dehydratase, in which the catalytic site of the enzyme is complexed with a putative cyclic intermediate composed of both substrate moieties, has been solved at 0.16 nm (1.6 A) resolution.

Clinically Important Features of Porphyrin and Heme Metabolism and the Porphyrias
Heme, like chlorophyll, is a primordial molecule and is one of the fundamental pigments of life. Disorders of normal heme synthesis may cause human diseases, including certain anemias (X-linked sideroblastic anemias) and porphyrias.

Structural studies of substrate and product complexes of 5-aminolaevulinic acid dehydratase from humans, Escherichia coli and the hyperthermophile Pyrobaculum calidifontis [PDF]
A number of X-ray analyses of an enzyme involved in a key early stage of tetrapyrrole biosynthesis are reported. Two structures of human 5-aminolaevulinate dehydratase (ALAD), native and recombinant, have been determined at 2.8 Å resolution, showing that
