Function
LPTA_ECOLI Involved in the assembly of lipopolysaccharide (LPS). Required for the translocation of LPS from the inner membrane to the outer membrane. May form a bridge between the inner membrane and the outer membrane, via interactions with LptC and LptD, thereby facilitating LPS transfer across the periplasm.[HAMAP-Rule:MF_01914][1] [2] [3] [4] [5]
