Summary The STAY‐GREEN (SGR) gene encodes Mg‐dechelatase which catalyzes the
conversion of chlorophyll (Chl) a to pheophytin (Pheo) a. This reaction is the first and most …

Chlorophyll a serves as a photosynthetic pigment in plants. Its degradation is initiated by the
extraction of the central Mg by the Mg-dechelatase enzyme, which is encoded by Stay …

Mg removal from chlorophyll by Mg-dechelatase is the first step of chlorophyll degradation.
Recent studies showed that in Arabidopsis, Stay Green (SGR) encodes Mg-dechelatase …

Pheophytin a is an essential component of oxygenic photosynthetic organisms because the
primary charge separation between chlorophyll a and pheophytin a is the first step in the …

The relationship between enzymes and substrates does not perfectly match the “lock and
key” model, because enzymes act on molecules other than their true substrate in different …

The first step in chlorophyll a degradation is the extraction of the central Mg. This reaction is
catalyzed by Mg-dechelatase encoded by Stay-Green (SGR) in land plants. SGR extracts …

Degradation of chlorophyll (Chl) by Chl catabolic enzymes (CCEs) causes the loss of green
color that typically occurs during senescence of leaves. In addition to CCEs, STAYGREEN1 …

Plants can dispose of organs such as leaves and recycle the nutrients in these organs into
new leaves, seeds, or storage organs. However, when separated from its photosystem …
