tRNA methyltransferases during embryogenesis in Musca domestica☆
[摘要] ActivityanddiversityofthetRNAmethyltransferaseswereexaminedduringembryogenesisofthehousefly,Muscadomestica.ArapidriseintheactivityofthetRNAmethyltransferaseswasobservedduringthefirst3hrofembryogenesis.Activityincreasedslowlyuntilthetenthhourofembryogenesisandthendeclineduntilhatchingat12hr.ThegreatestdiversityoftRNAmethyltransferases,asindicatedbyextentofmethylation,existedat6hrofembryogenesis;theleastdiversitywasobservedin1-hrembryos,while12-hrembryosshowedintermediatelevels.InhibitionofembryonictRNAmethyltransferasesathighconcentrationsofenzymewasobservedinallextractsexamined.
