Purification and properties of the carbonic anhydrase of Rhodospirillum rubrum

Archives of Microbiology, 138(2), 113–118.

By: S. Gill *, P. Fedorka-Cray *, R. Tweten * & B. Sleeper*

TL;DR: The carbonic anhydrase of Rhodospirillum rubrum has been purified to apparent homogeneity and some of its properties have been determined, and inhibition patterns indicated that histidine, sulfhydryl, lysine and serine residues were important for enzymatic activity. (via Semantic Scholar)
