Align MalK; aka Sugar ABC transporter, ATP-binding protein, component of The maltose, maltotriose, mannotetraose (MalE1)/maltose, maltotriose, trehalose (MalE2) porter (Nanavati et al., 2005). For MalG1 (823aas) and MalG2 (833aas), the C-terminal transmembrane domain with 6 putative TMSs is preceded by a single N-terminal TMS and a large (600 residue) hydrophilic region showing sequence similarity to MLP1 and 2 (9.A.14; e-12 & e-7) as well as other proteins (characterized)

This GapMind analysis is from Sep 17 2021. The underlying query database was built on Sep 17 2021.
Each pathway is defined by a set of rules based on individual steps or genes. Candidates for each step are identified by using ublast (a fast alternative to protein BLAST) against a database of manually-curated proteins (most of which are experimentally characterized) or by using HMMer with enzyme models (usually from TIGRFam). Ublast hits may be split across two different proteins.
A candidate for a step is "high confidence" if either:
Otherwise, a candidate is "medium confidence" if either:
Other blast hits with at least 50% coverage are "low confidence."
Steps with no high- or medium-confidence candidates may be considered "gaps." For the typical bacterium that can make all 20 amino acids, there are 1-2 gaps in amino acid biosynthesis pathways. For diverse bacteria and archaea that can utilize a carbon source, there is a complete high-confidence catabolic pathway (including a transporter) just 38% of the time, and there is a complete medium-confidence pathway 63% of the time. Gaps may be due to:
GapMind relies on the predicted proteins in the genome and does not search the six-frame translation. In most cases, you can search the six-frame translation by clicking on links to Curated BLAST for each step definition (in the per-step page).
