3.1.3.5	5'-nucleotidase	aggregation stage	-	653111	
4.6.1.2	guanylate cyclase	aggregation stage	soluble guanylyl cyclase sGC is mainly expressed during aggregation phase	667002	
4.6.1.2	guanylate cyclase	aggregation stage	upon development, mRNA expression of guanylyl cyclase GCA decreases about 5fold during aggregation and subsequently rises, reaching a maximum during the slug stage	667002
