External fertilization is considered to be the primitive condition in metazoans. The spermatozoa of such organisms typically display a common primitive- type morphology that is present in a range of phyla. These spermatozoa are extremely polarized ce

Spermatozoa of the horseshoe crab, Limulus polyphemus, contained high activities of arginine kinase (AK), the bulk of which was completely solubilized in buffer lacking detergent. Sperm AK, along with the fast isoform of muscle AK, were purified to h

Dissociation constants for MgATP [Kd(MgATP)] were measured with the combined techniques of spectrophotometry using the metallochromic dye, Antipyrylazo III, and phosphorus nuclear magnetic resonance (31P-NMR) spectroscopy. Values of the Kd(MgATP) wer

Mitochondria from the heart of the horseshoe crab,Limulus polyphemus, contained two distinct activities of arginine kinase (AK). Approximately 50% of AK activity consisted of a fast electrophoretic form (AKmf) which was easily extractable from mitoch

▪ Abstract Phosphagens are phosphorylated guanidino compounds that are linked to energy state and ATP hydrolysis by corresponding phosphagen kinase reactions: phosphagen + MgADP + H+↔ guanidine acceptor + MgATP. Eight different phosphagens (and c

A diverse array ofphosphagen kinases [arginine kinase (AK), lombricine kinase (LK)], glycocyamine kinase (GK), taurocyamine kinase (TK), and creatine kinase (CK) is ,found in the animal kingdom (see reJ: 1 for a review). These reactions appear to jun

Proton (1H) and phosphorus (31P) nuclear magnetic resonance (NMR) spectroscopy were used to investigate the mode of transport of L-lactate across the plasma membranes of the abdominal extensor muscles of the spiny lobster Panulirus argus. Individual
