Periplasmic carbonic anhydrase structural gene (Cah1) mutant in chlamydomonas reinhardtii

abstract：:The addition of primary amines to the growth medium of the unicellular green alga Chlamydomonas reinhardtii disrupts cell wall assembly in both vegetative and zygotic cells. Primary amines are competitive inhibitors of the protein-cross-linking activity of transglutaminases. Two independent assays for transglutaminase...
