Characterization of a protein factor which causes form interconversion of ornithine decarboxylase in Physarum polycephalum
(Northern Illinois University, 1980)
The first and rate limiting step in polyamine biosynthesis is the conversion of ornithine to putrescine by the enzyme ornithine decarboxylase(E.C. 18.104.22.168). Upon addition of spermidine or spermine to crude homogenates of ...
Purification of ornithine decarboxylase from Physarum polycephalum with characterization and quantitation of the catalytic unit utilizing 14 C-αdifuoromethylornithine
(Northern Illinois University, 1981)
Ornithine decarboxylase (L-ornithine carboxy-lyase, E.C. 22.214.171.124) is the rate limiting enzyme of the polyamine biosynthetic pathway in eukaryotic cells. The enzyme's lability and low intracellular concentration (<0.02% ...
