例文
- ATP Binding Cassette or efflux transporters mediate the transport of substrates across cell membranes against a concentration gradient.
- These genes are placed into two different categories : ABC ( ATP binding cassette ) transporters and PTS ( phosphotransferase system ) transporters.
- ABC transporters are minimally constituted of two conserved regions : a highly conserved ATP binding cassette ( ABC ) and a less conserved transmembrane domain ( TMD ).
