Two Arabidopsis ADP-glucose pyrophosphorylase large subunits (APL1 and APL2) are catalytic.

ADP-glucose (Glc) pyrophosphorylase (ADP-Glc PPase) catalyzes the first committed step in starch biosynthesis. Higher plant ADP-Glc PPase is a heterotetramer (alpha(2)beta(2)) consisting of two small and two large subunits. There is increasing evidence that suggests that catalytic and regulatory properties of the enzyme from higher plants result from the synergy of both types of subunits.

[Attention models to somatic symptoms without organic cause: from physiopathologic disorders to malaise of women].

Somatic symptoms of no identifiable organic cause remain medically unexplained and have been delved into to only a limited degree from a biologicist conception of health. Different critical theories study contextual, gender-related and subjective factors for Somatic Symptoms of No Identifiable Organic Cause and their care models. This study has been aimed at reviewing published Spanish studies (1995-2002) exploring explanatory SSNIOC's by relating them to the underlying health theories.
