Expression, purification and characterisation of protoporphyrinogen oxidases from diverse species [PDF]

open access: yes, 2000
Bibliography: leaves 163-203.This work involved the characterisation of protoporphyrinogen oxidase (PPO), the penultimate enzyme in haem biosynthesis, from Bacillus subtilis, Myxococcus xanthus, and human. A defect in human PPO causes variegate porphyria,

Uneven distribution of cobamide biosynthesis and dependence in bacteria predicted by comparative genomics. [PDF]

open access: yes, 2019
The vitamin B12 family of cofactors known as cobamides are essential for a variety of microbial metabolisms. We used comparative genomics of 11,000 bacterial species to analyze the extent and distribution of cobamide production and use across bacteria ...

Kinetic evaluation of human cloned coproporphyrinogen oxidase using a ring isomer of the natural substrate [PDF]

open access: yes, 2005
Background: The enzyme coproporphyrinogen oxidase (copro\u27gen oxidase) converts coproporphyrinogen-Ill (GIII) to protoporphyrinogen-IX via an intermediary monovinyl porphyrinogen. The A ring isomer coproporphyrinogen-IV (C-IV) has previously been shown

Synthesis, secretion, and perception of abscisic acid regulates stress responses in \u3ci\u3eChlorella sorokiniana\u3c/i\u3e [PDF]

open access: yes, 2018
Abscisic acid (ABA) is a phytohormone that has been extensively characterized in higher plants for its roles in seed and bud dormancy, leaf abscission, and stress responses.
