Characterisation of a common hotspot variant in acute intermittent porphyria sheds light on the mechanism of hydroxymethylbilane synthase function
Christie, Marthe S.; Laitaoja, Mikko; Aarsand, Aasne Karine; Kallio, Juha Pekka; Bustad, Helene J. (Journal article; Peer reviewed, 2022)Hydroxymethylbilane synthase (HMBS) is the third enzyme involved in haem biosynthesis, in which it catalyses the formation of tetrapyrrole 1-hydroxymethylbilane (HMB). In this process, HMBS binds four consecutive substrate ... -
Characterization of porphobilinogen deaminase mutants reveals that arginine-173 is crucial for polypyrrole elongation mechanism
Bustad, Helene J.; Kallio, Juha Pekka; Laitaoja, Mikko; Toska, Karen; Kursula, Inari; Martinez, Aurora; Jänis, Janne (Journal article; Peer reviewed, 2021)Porphobilinogen deaminase (PBGD), the third enzyme in the heme biosynthesis, catalyzes the sequential coupling of four porphobilinogen (PBG) molecules into a heme precursor. Mutations in PBGD are associated with acute ...
