Notes on Genus: Bdellomicrovirus
Type member: Bdellovibrio phage MAC 1
This is one of the genera in the family Microviridae
. Members infect infect epsilon-purple bacteria (Bdellovibrio
Virions isometric (icosahedral), not enveloped, 26-32 nm in diameter with small surface projections.
Monopartite, positive sense, circular ssDNA about 5 kb in length.
Genus Genomic Organization
Only Bdellovibrio phage phiMH2K has been sequenced and this has 6 closely spaced major ORFs, with up to 5 other minor ORFs identified by computer prediction which may or may not be expressed:
|1||60.1||Major coat protein P1|
|5||4.4||Putative DNA binding protein|
The five minor ORFs identified are nested within the others: Z (7.5 kDa), Y (7.2 kDa), X (8.0 kDa), W (5.9 kDa) and N (12.0 kDa).
Type Member Genomic Organization
There are no sequence data for the type member.
