24449654-1	2014	Arabidopsis HEMA1 and HEMA2 encode glutamyl-tRNA reductase (GluTR) 1 and 2, the two isoforms of the initial enzyme of tetrapyrrole biosynthesis.	Tetrapyrroles	118-130	Glutamyl-tRNA reductase family protein	Arabidopsis thaliana	22-27	
17416636-0	2007	Induction of isoforms of tetrapyrrole biosynthetic enzymes, AtHEMA2 and AtFC1, under stress conditions and their physiological functions in Arabidopsis.	Tetrapyrroles	25-37	Glutamyl-tRNA reductase family protein	Arabidopsis thaliana	60-67	
17416636-1	2007	In the tetrapyrrole biosynthetic pathway, isoforms of glutamyl-tRNA reductase (HEMA2) and ferrochelatase1 (FC1) are mainly expressed in nonphotosynthetic tissues.	Tetrapyrroles	7-19	Glutamyl-tRNA reductase family protein	Arabidopsis thaliana	79-84	
17416636-11	2007	These results suggest the existence of the tetrapyrrole biosynthetic pathway controlled by AtHEMA2 and AtFC1, which normally functions for heme biosynthesis in nonphotosynthetic tissues, but is induced in photosynthetic tissues under oxidative conditions to supply heme for defensive hemoproteins outside plastids.	Tetrapyrroles	43-55	Glutamyl-tRNA reductase family protein	Arabidopsis thaliana	91-98	
12139011-11	2002	The roles of HEMA1 and HEMA2 in meeting cellular tetrapyrrole requirements are discussed.	Tetrapyrroles	49-61	Glutamyl-tRNA reductase family protein	Arabidopsis thaliana	23-28
