An external combustion engine (EC engine) is a reciprocating heat engine where a working fluid, contained internally, is heated by combustion in an external source, through the engine wall or a heat exchanger. The fluid then, by expanding and acting on the mechanism of the engine, produces motion and usable work. [1]
EC 2.4.1.109: dolichyl-phosphate-mannose—protein mannosyltransferase; EC 2.4.1.110: tRNA-queuosine β-mannosyltransferase; EC 2.4.1.111: coniferyl-alcohol glucosyltransferase; EC 2.4.1.112: The protein referred to in this entry is now known to be glycogenin so the entry has been incorporated into EC 2.4.1.186, glycogenin glucosyltransferase
