Spermatozoa - 새창 Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.
Synonyms : Spermatozoon, X-Bearing Sperm, X-Chromosome-Bearing Sperm, Y-Bearing Sperm, Y-Chromosome-Bearing Sperm, Sperm, X-Bearing, Sperm, X-Chromosome-Bearing, Sperm, Y-Bearing, Sperm, Y-Chromosome-Bearing, Sperms, X-Bearing, Sperms, X-Chromosome-Bearing, X Bearing Sperm
Spermidine - 새창 A polyamine formed from putrescine. It is found in almost all tissues in association with nucleic acids. It is found as a cation at all pH values, and is thought to help stabilize some membranes and nucleic acid structures. It is a precursor of spermine.
Synonyms :
Spermidine Synthase - 새창 An enzyme that catalyzes the transfer of the propylamine moiety from 5'-deoxy-5'-S-(3-methylthiopropylamine)sulfonium adenosine to putrescine in the biosynthesis of spermidine. The enzyme has a molecular weight of approximately 73,000 kDa and is composed of two subunits of equal size.
Synonyms : Putrescine Aminopropyltransferase, Aminopropyltransferase, Putrescine, Synthase, Spermidine, Synthetase, Spermidine, Transferase, Propylamine
Spermine - 새창 A biogenic polyamine formed from spermidine. It is found in a wide variety of organisms and tissues and is an essential growth factor in some bacteria. It is found as a polycation at all pH values. Spermine is associated with nucleic acids, particularly in viruses, and is thought to stabilize the helical structure.
Synonyms :
Spermine Synthase - 새창 An enzyme that catalyzes the transfer of the propylamine moiety from 5'-deoxy-5'-S-(3-methylthiopropylamine)sulfonium adenosine to spermidine in the biosynthesis of spermine. It has an acidic isoelectric point at pH 5.0. EC 2.5.1.22.
Synonyms : Spermidine Aminopropyltransferase, Aminopropyltransferase, Spermidine, Synthase, Spermine, Synthetase, Spermine
