1954Cohen & Hirsch in Jrnl. Bacteriol. LXVII. 182/2 This paper describes an enzyme system synthesizing threonine from homoserine; we have called it threonine synthase. 1961Rep. Commission on Enzymes v. 37 Enzymes removing groups from substrates non-hydrolytically, leaving double bonds (or adding groups to double bonds) will be called ‘lyases’... ‘Synthetase’ will not be used for any enzymes in this class; where it has been customary, ‘synthase’ will be used instead. 1976Ann. Rev. Microbiol. XXX. 212 An alternate view is that cystspecific RNA synthesis during encystment is not necessary for the formation of cellulose synthase. 1979Science 7 Dec. 1149/3 The ATP synthase is a chemiosmotic membrane-located reversible ATPase. |
