Localization of Carboxypeptidase I in Germinating Barley Grain 1
Activity measurements and Northem blot hybridizations were used to study the temporal and spatial expression of carboxypeptidase I in germinating grains of barley (Hordeum vulgare L. cv Himalaya). In the resting grain no carboxypeptidase I activity was found in the aleurone layer, scutellum, or starchy endosperm. During germination high levels of enzyme activity appeared in the scutellum and in...

متن کاملUptake of Glycyiglycine by the Scuteilum of Germinating Barley
The scuteUa separated from germinating barley grains (Hordewn vagare L. cv. Himalaya) took up the dipeptide 14Clglycylglycine (Gly-Gly) rapidly from incubation media. The pH optimum of the process was about 4.5, and the rate of uptake conformed to Michaelis-Menten kinetics with an apparent Km of 2.3mm and V. of41 imole gram-l hour-'. The uptake was strongly inhibited by dinitrophenol and cyanid...

متن کاملAmino Acid and Peptide uptake in the scutella of germinating grains of barley, wheat, rice, and maize.
Scutella separated from germinating grains of barley (Hordeum vulgare L.), wheat (Triticum aestivum L.), rice (Oryza sativa L.), and maize (Zea mays L.) took up the four amino acids and the three peptides tested from incubation media. The uptake of amino acids by wheat scutella was similar to that of barley scutella and was via at least four uptake systems: two nonspecific amino acid uptake sys...
