unidirectional conjugation

PMID:18539740[1]

ECO:0000315

P

Wild type TrwK showed a conjugation frequencies 4x10^-1 where a deletion in TrwK showed a conjugation frequency of 4x10^-6. This value is closer to the negative control of 4x10^-7 showing that TrwK is needed for conjugation.

integral to membrane

PMID:18539740[1]

ECO:0000314

C

TrwK does not behave as an integral membrane protein(Paragraph) + Table 2 Researchers found that the addition of detergent and phospholipids didn't affect the solubility of TrwK in solution from which they infered that unlike homologs, TrwK was not an integral membrane protein.
