The Functions of Chloroplast Glutamyl-tRNA in Translation and Tetrapyrrole Biosynthesis [PDF]
, 2020 The chloroplast glutamyl-tRNA (tRNAGlu) is unique in that it has two entirely different functions. In addition to acting in translation, it serves as substrate of glutamyl-tRNA reductase, the enzyme catalyzing the committed step in the tetrapyrrole ...

Leishmania major possesses a unique HemG-type protoporphyrinogen IX oxidase
Bioscience Reports, 2014 Leishmania major was proposed to either utilize haem from its host or partially synthesize the tetrapyrrole from host provided precursors. However, only indirect evidence was available for this partial late haem biosynthetic pathway. Here, we demonstrate

Synthesis, properties and reactivity of an ortho-phenylene-cyclopentene-bridged tetrapyrrole [PDF]
, 2021 Increasing the number of meso-methine carbons of porphyrin has led to a creation of a series of vinylogous expanded porphyrins, while the introduction of an ortho-phenylene-unit as a pyrrole-connecting two-carbon bridge usually leads to prevention of ...

Crystal structure of 4-(methoxycarbonyl)phenylboronic acid
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title compound, C8H9BO4, the methoxycarbonyl group is rotated out of the plane of the benzene ring by 7.70 (6)°. In the crystal, molecules are linked via pairs of O—H...O hydrogen bonds, involving the boronic acid OH groups, forming inversion ...

Prevention of poxvirus infection by tetrapyrroles [PDF]
BMC Infectious Diseases, 2003 Prevention of poxvirus infection is a topic of great current interest. We report inhibition of vaccinia virus in cell culture by porphyrins and phthalocyanines. Most previous work on the inhibition of viruses with tetrapyrroles has involved photodynamic mechanisms.

Light regulation of tetrapyrrole biosynthesis in Arabidopsis [PDF]
, 2007 The tetrapyrrole biosynthesis pathway results in the synthesis of both haem and chlorophyll and tight regulation of this pathway during de-etiolation is critical for the safe biogenesis of the photosynthetic apparatus.

A mathematical model of the tetrapyrrole biosynthesis pathway [PDF]
, 2007 The tetrapyrrole biosynthesis pathway is a key part in chlorophyll production and is essential for plant survival. It involves numerous interacting compounds and, crucially, light.
