MipA (YeaF) (Vollmer et al., 1999).  This outer membrane protein of 248 aas and 10 TM β-strands is involved in antibiotic resistance (Li et al. 2015).  It is also an MltA (outer membrane lytic transglycosylase (P0A935))-interacting protein (van Straaten et al. 2005; Vollmer et al. 1999).

1.B.93.1.4









N-terminal DUF2141 domain/C-terminal MipA domain protein.  The N-terminal domain may be an artifactual fusion of a full length DUF2141 domain with a full length putative C-terminal porin domain, but this seems less likely since the same fusion has been observed in another family member (TC# 1.B.93.2.8).

1.B.93.2.1









Uncharacterized DUF2141 protein of 153 aas.  This protein is homologous only to the N-terminal domain in 9.B.99.1.4, but no other members of subfamily 9.B.99.1.  It is therefore not homologous to other members of subfamily 9.B.99.1.  The N-terminal domain of 9.B.99.1.4 may be artifactual.

Uncharacterized DUF2141 protein of 157 aas.  This protein is homologous to the N-terminal domain in 9.B.99.1.4, but not to other members of subfamily 9.B.99.1. The N-terminal domain of 9.B.99.1.4 may be a fusion of a DUF2141 domain with a putative C-terminal porin domain of the MipA type, distant from other proteins listed in subfamily 1.B.93.1.

1.B.93.2.8









Uncharacterized fatty acid hydroxylase domain protein of 711 aas and 7 TMSs in a 6 + 1 TMS arrangement.  This protein has three domains, first an integral membrane fatty acid hydroxylase domain, second, a DUF2141 domain, and third, a MipA domain with an N-terminal TMS. The protein with TC# 1.B.93.1.4 has the latter two domains fused together in the same order as for this protein.
