Phenotypes of a mutant

• mutants respond poorly to multiple germinants, impaired in early stage of germination [Pubmed|17720779]

The protein

Protein family

• eamA transporter family (according to Swiss-Prot)

[SW|Localization]

• cell membrane (according to Swiss-Prot), first assembled in foci, then spread around the developing spore in a [protein|825AD8D4315A85CD384F9AF6AD894E38E57C88F7|CotE]-dependent manner [Pubmed|17720779]
