Phenotypes of a mutant
not essential for pellicle biofilm formation, but mutant is outcompeted by the wild-type strain when competed during pellicle formation [Pubmed|26122431]
NCIB3610 ''hemAT'' mutant has higher fitness than ''[gene|E0BB77C8F1220E931D16A1FA6B75AE8907C76FDB|hag]'' mutant during pellicle formation [Pubmed|26122431]
NCIB3610 ''hemAT''-''[gene|E0BB77C8F1220E931D16A1FA6B75AE8907C76FDB|hag]'' double mutant has similar fitness to single ''[gene|E0BB77C8F1220E931D16A1FA6B75AE8907C76FDB|hag]'' mutant during pellicle formation [Pubmed|26122431]
additional information
the gene readily acquires mutations during adaptation to growth as pellicle biofilm [pubmed|37768063]
