| abstract |
The invention relates to a mutant protein comprising at least a fragment of a mutant dimethylarginine dimethylaminohydrolase (DDAH) enzyme, wherein the fragment possesses an affinity for asymmetric N,N-dimethyl arginine (ADMA) and/or L,N-monomethylarginine (LNMMA), which exists at lower plasma levels than ADMA, and is deficient in hydrolyzing ADMA or LNMMA to citrulline, releasing citrulline, or both. |
