the proteolytic activity of Clp protease counteracts GBP binding to assure the appropriate content of GluTR and the adequate amino levulinic acid synthesis for chlorophyll and heme in higher plants.
Title: Posttranslational Control of ALA Synthesis Includes GluTR Degradation by Clp Protease and Stabilization by GluTR-Binding Protein.

a ternary complex composed of the C-terminal tetratricopepetide-repeat domain of FLU, GBP, and GluTR, is reported
Title: The Arabidopsis glutamyl-tRNA reductase (GluTR) forms a ternary complex with FLU and GluTR-binding protein.

characterize the FLU-GluTR interaction by solving the crystal structures of the uncomplexed TPR domain of FLU (FLU(TPR)) at 1.45-A resolution and the complex of the dimeric domain of GluTR bound to FLU(TPR) at 2.4-A resolution
Title: The Non-canonical Tetratricopeptide Repeat (TPR) Domain of Fluorescent (FLU) Mediates Complex Formation with Glutamyl-tRNA Reductase.

A gene encoding aminolevulinate synthase (ALA-S) in yeast (Saccharomyces cerevisiae YHem1) was introduced into the genome of tobacco (Nicoliana tabacum) under the control of Arabidopsis thaliana HemA1 gene promoter (AtHemA1 P).
Title: Expression of yeast Hem1 controlled by Arabidopsis HemA1 promoter enhances leaf photosynthesis in transgenic tobacco.

HEMA1 overexpression in etiolated and dark-grown Arabidopsis and tobacco seedlings leads to additional accumulation of protochlorophyllide.
