TLDR
Ycf54 is essential for the activity and stability of the oxidative cyclase, and levels of the cyclase component Sll1214 and the Chl biosynthesis enzymes Mg-protoporphyrin IX methyltransferase and protochlorophyllide reductase are significantly impaired in the ycf54 mutant.About:

TL;DR: A link between chlorophyll biosynthesis and the Sec/YidC-dependent cotranslational insertion of nascent photosystem polypeptides into membranes is revealed and it is expected that this close physical linkage coordinates the arrival of pigments and nascent apoproteins to produce photosynthetic pigment-protein complexes with minimal risk of accumulating phototoxic unbound chlorophyLLs.

Chloroplast evolution, structure and functions
Poul Erik Jensen,Dario Leister +1 more
TL;DR: This review considers a selection of recent advances in chloroplast biology, and discusses the first successful synthetic biology approaches that resulted in chloroplasts in which electrons from the photosynthetic light reactions are fed to enzymes derived from secondary metabolism.

Generic assignments, strain histories, and properties of pure cultures of cyanobacteria
TL;DR: Revisions are designed to permit the generic identification of cultures, often difficult through use of the field-based system of phycological classification, and are both constant and readily determinable in cultured material.

Determination of accurate extinction coefficients and simultaneous equations for assaying chlorophylls a and b extracted with four different solvents: verification of the concentration of chlorophyll standards by atomic absorption spectroscopy
TL;DR: In this paper, the extinction coefficients for chlorophylls a and b in diethylether (Smith, J.H. and Benitez, A.V., eds.), used in this paper as primary standards, were verified by magnesium determination using atomic absorbance spectrophotometry.

Tetrapyrrole Biosynthesis in Higher Plants
Ryouichi Tanaka,Ayumi Tanaka +1 more
TL;DR: Recent progress in the research of tetrapyrrole biosynthesis from a cellular biological view consists of biochemical, structural, and genetic analyses, which contribute to understanding of how the flow and the synthesis of tetrapeyrrole molecules are regulated and how the potentially toxic intermediates of tetramyrrole synthesis are maintained at low levels.
