EXPRESSION
ORGANISM
UNIPROT
LITERATURE
a rapidly decreased content of soluble enzyme is observed in wild type seedlings within the first 3 h in darkness
-
enzyme abundance increases specifically in response to heme deficiency
etiolation of initially green dark-grown larch cotyledons is connected with decreasing content of glutamyl-tRNA reductase
-
expression of HEMA1 that encodes the dominant GluTR in the photosynthetic tissues is regulated by light
expression profiles in the first hours of deetiolation of Arabidopsis seedlings show an abundance of GluTR that gradually increased with chlorophyll biosynthesis
-
stromal enzyme content reaches a maximum at day 14 during short days (10 h light/14 h darkness) and continuous light conditions, before it visibly decreases at day 40. Maximum membrane-bound enzyme is found at day 28 during short days and at days 14 and 28 under continuous light
-
the relative amount of GluTR is similar both in the dark-grown and light/dark-grown gabaculine-treated seedlings
