Species-specific charge forms of phenylethanolamine N-methyltransferase. 1985

D H Park, and T H Joh

Isoelectric points (pI) of phenylethanolamine N-methyltransferase (PNMT) from two species, cow and rat, were determined by chromatofocusing. Bovine PNMT has 5 different charge isozymes ranging from 5.4 to 6.2. In contrast, rat PNMT has only a single charge form of pI 4.8. There is no common isoelectric point of PNMT from both species and there is no tissue variation in the isoelectric point.

D010625	Phenylethanolamine N-Methyltransferase	A methyltransferase that catalyzes the reaction of S-adenosyl-L-methionine and phenylethanolamine to yield S-adenosyl-L-homocysteine and N-methylphenylethanolamine. It can act on various phenylethanolamines and converts norepinephrine into epinephrine. (From Enzyme Nomenclature, 1992) EC 2.1.1.28.

D000311	Adrenal Glands	A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
