The Cover pi
cture is an artisti
c view of the highly sele
ctive Nω-phosphorylation of L-arginine
catalyzed by arginine kinase.In their Full Paper, B. S
choenenberger et al. demonstrate that a highly a
ctive and stable arginine kinase, prepared by
cloning and expressing the gene for
ArgK from
Limulus polyphemus in
E. coli, ATP-regeneration using the phosphoenolpyruvate/pyruvate kinase system and rea
ction monitoring by
31P-NMR enable the development of a
convenient method for the bio
catalyti
c Nω-phosphorylation of L-arginine. Our results show that tedious multi-step
chemi
cal pro
cedures for the synthesis of
Nω-phospho-L-arginine
can be simplified by a straightforward and highly effi
cient one-step arginine kinase-
catalyzed phosphorylation of L-arginine. More information
