Anatomical context of Brachyura

• Affinity-based purification and characterization of the collagenolytic serine protease 1 from Uca pugilator (fiddler crab) hepatopancreas shows that the enzyme cleaves the native bovine alpha 1(I) collagen chain carboxyl-terminal to Gln and Arg residues adjacent to the metallocollagenase site [19].

• In each case the label was incorporated into menaquinone-4.[2-14C]Mevalonate was incorporated into menaquinone-4 in the crab (Carcinus maenas) only in the presence of menadione, the organism presumably being unable to synthesize the naphthaquinone nucleus [26].

Gene context of Brachyura

• Purified recombinant O. sagaranensis Uca displayed ATP-dependent carboxylase activity towards urea (V(max) = 21.2 micro mol mg(-1) min(-1)) but not towards acetyl coenzyme A (acetyl-CoA) and propionyl-CoA, indicating that the gene encoded a bona fide UCA and not an acetyl-CoA or propionyl-CoA carboxylase [27].
