Agmatine

Agmatine sulfate [5-guanidinopent-l-ylamine sulfate] [2482-00-0] M 228.3, m 231 , pKeikd -9.1, pKesi(2) 13.0. Crystd from aqueous MeOH. [Pg.98]

The nature of the basic functions was defined by hydrolysis of M in 2N hydrochloric acid at 100°C. This furnished agmatine (I) which was characterized as its picrate and hydrochloride and also by degradation to putrescine (II). [Pg.87]

IEC was applied to determine biogenic polyamines such as putrescine (4a), cadaverine (4b), tyramine (5), histamine (6), spermidine (38), agmatine (39) and tryptamine (40), contained in aqueous trichloroacetic extracts of leafy vegetables, such as cabbage and lettuce. A cation exchange column loaded with potassium ions and a special buffer were used. Spermidine (38) was the major amine detected in this group (7-15 Xg/g fresh weight)144. [Pg.1069]

This enzyme [EC 3.5.3.12], also known as agmatine imi-nohydrolase, catalyzes the hydrolysis of agmatine to produce A/ -carbamoylputrescine and ammonia. The plant enzyme also catalyzes the reactions of EC 2.1.3.3 (ornithine carbamoyltransferase), EC 2.1.3.6 (putrescine car-bamoyltransferase) and EC 2.122 (carbamate kinase), thereby functioning as a putrescine synthase, converting agmatine and ornithine into putrescine and citrulline, respectively. [Pg.40]

This enzyme [EC 4.1.1.19] uses pyridoxal phosphate as a cofactor in catalyzing the conversion of arginine to carbon dioxide and agmatine. [Pg.63]

This enzyme [EC 2.1.3.6] catalyzes the reaction of carbamoyl phosphate with putrescine to produce orthophosphate and A-carbamoylputrescine. The plant enzyme will also catalyze the reactions of ornithine carbamoyltransferase, carbamate kinase, and agmatine deimmase. [Pg.589]
