'Allo 'Allo! who did not appear in the reunion at all (where the actor or actress who played the character originally was then alive) were Private Helga Geerhart (played by Kim Hartman) and Herr Engelbert von Smallhausen (played by John Louis Mansi). Jeremy Lloyd wrote the new material. At the end of each show, in common with "Dad's Army", "Are You Being Served?", "It Ain't Half Hot Mum" and "Hi-de-Hi!", the end credits begin with the caption "You have been watching (in order of appearance)", followed by a short vignette shot of each of the main characters with the actor's name displayed
L-allo-threonine aldolase L-allo-threonine aldolase L-allo-threonine aldolase (GLY1, ) is an enzyme catalyzing the conversion between L-allothreonine (unusual stereoisomer) on one side and glycine plus acetaldehyde on another side. Artificial disabling (knockout) of this enzyme in wild bacteria has no significant effect. However such disabling suppresses the growth of mutants that already lack other enzyme, serine hydroxymethyltransferase. Hence L-allo-threonine aldolase provides the alternative pathway for cellular glycine when serine hydroxymethyltransferase is inert. "E.coli" L-allo-threonine aldolase is a highly termostable enzyme (survives 60 degrees C), this can be used for purification. The enzyme is specific for L-allothreonine and can not act on the more
