Enigmatic Evolutionary History of Porphobilinogen Deaminase in Eukaryotic Phototrophs [PDF]

open access: goldBiology, 2021
In most eukaryotic phototrophs, the entire heme synthesis is localized to the plastid, and enzymes of cyanobacterial origin dominate the pathway.

Structural insights into E. coli porphobilinogen deaminase during synthesis and exit of 1-hydroxymethylbilane.

open access: goldPLoS Computational Biology, 2014
Porphobilinogen deaminase (PBGD) catalyzes the formation of 1-hydroxymethylbilane (HMB), a crucial intermediate in tetrapyrrole biosynthesis, through a step-wise polymerization of four molecules of porphobilinogen (PBG), using a unique dipyrromethane ...

PORPHOBILINOGEN DEAMINASE Deficiency Alters Vegetative and Reproductive Development and Causes Lesions in Arabidopsis [PDF]

open access: yesPLoS ONE, 2013
The Arabidopsis rugosa1 (rug1) mutant has irregularly shaped leaves and reduced growth. In the absence of pathogens, leaves of rug1 plants have spontaneous lesions reminiscent of those seen in lesion-mimic mutants; rug1 plants also express cytological ...

Isolation and Characterization of SPOTTED LEAF42 Encoding a Porphobilinogen Deaminase in Rice [PDF]

open access: goldPlants, 2023
The formation and development of chloroplasts play a vital role in the breeding of high-yield rice (Oryza sativa L.). Porphobilinogen deaminases (PBGDs) act in the early stage of chlorophyll and heme biosynthesis.

Acute intermittent porphyria: A case report [PDF]

open access: yesVojnosanitetski Pregled, 2021
Introduction. Acute intermittent porphyria is a rare inherited metabolic disorder caused by a decreased level of porphobilinogen deaminase. Subsequent accumulation of by-products in neural elements causes a classic triad of abdominal pain, neurological ...

Profiling of Serum Metabolites of Acute Intermittent Porphyria and Asymptomatic HMBS Mutation Carriers

open access: yesCells, 2021
This study aims to present the serum metabolite profiles of patients with acute intermittent porphyria (AIP) and identify specific metabolites that could potentially discriminate between AIP, asymptomatic HMBS mutation carriers, and healthy individuals ...

Acute Intermittent Porphyria (AIP): A Difficult Diagnosis

open access: yesMAMC Journal of Medical Sciences, 2021
Acute intermittent porphyria (AIP) is a rare autosomal dominant disorder of heme biosynthesis but usually carry a good prognosis, if the condition is picked up early.

Mechanisms of Neuronal Damage in Acute Hepatic Porphyrias

open access: yesDiagnostics, 2021
Porphyrias are a group of congenital and acquired diseases caused by an enzymatic impairment in the biosynthesis of heme. Depending on the specific enzyme involved, different types of porphyrias (i.e., chronic vs. acute, cutaneous vs.
