2.A.26.1.3









Branched chain amino acid:H+ symporter
Bacteria
Bacillota
BrnQ of Lactobacillus delbrueckii
2.A.26.1.4









The branched chain amino acid transporter BrnQ (transports Leu, Ile, Val, Phe, and Met) (Braun et al., 2008).

Bacteria
Chlamydiota
BrnQ of Chlamydia trachomatis (O84558)
2.A.26.1.5









LIVCS family member of 429 aas and 12 TMSs.

Bacteria
Bacillota
LIV transporter of Blautia hydrogenotrophica
2.A.26.1.6









Uncharacterized protein of 430 aas and 12 TMSs.

Bacteria
Campylobacterota
UP of Arcobacter butzleri
2.A.26.1.7









LIV transporter of 411 aas and 12 TMSs

Bacteria
Mycoplasmatota
LIV transporter of Mycoplasma sp.
2.A.26.1.8









LIV transporter of 445 aas and 12 TMSs.

Bacteria
Thermodesulfobacteriota
lIV transporter of Desulfovibrio desulfuricans
2.A.26.1.9









Branched chain amino acid (Leucine, Isoleucine, Valine) transporter of 456 aas and 12 TMSs, BrnQ (Trip et al. 2013).

Bacteria
Bacillota
BrnQ of Lactococcus lactis
2.A.26.1.10









Branched chain amino acid transporter 2 of 439 aas and 12 TMSs, BrnQ (Guardiola et al. 1974). The brnQ gene can be mutated to give rise to threonine tolerance (Radi et al. 2022). However the wild type protein takes up threonine (in addition to leucine, isoleucine and valine) but with low affinity and high flux (Khozov et al. 2023). 

Bacteria
Pseudomonadota
BrnQ of E. coli
