malfunction
metabolism
physiological function
-
HCAR functions in Chl degradation as a component of the SGRCCE-LHCII complex during leaf senescence
-
insertion mutant hcar-1 leaf cells lose membrane integrity during dark incubation
malfunction
-
HCAR-overexpressing plants exhibit accelerated leaf yellowing and hcar mutants stay green during dark-induced senescence
-
cyanobacterial 3,8-divinyl chlorophyllide reductase (DVR) has 7-hydroxymethyl chlorophyll a reductase activity. Enzyme participates in the Chl cycle in green plants
metabolism
the enzyme is required for the degradation of light-harvesting complexes and is necessary for efficient photosynthesis by balancing the chlorophyll a/b ratio
