Finding step TM1750 for D-mannose catabolism in Klebsiella michiganensis M5al

4 candidates for TM1750: mannose ABC transporter, ATPase component 2

Score Gene Description Similar to Id. Cov. Bits Other hit Other id. Other bits
med BWI76_RS17220 oligopeptide ABC transporter ATP-binding protein OppF TM1750, component of Probable mannose/mannoside porter. Induced by beta-mannan (Conners et al., 2005). Regulated by mannose-responsive regulator manR (characterized) 51% 95% 313.9 OppF aka STM1742, component of Oligopeptide porter (also takes up amino glycoside antibiotics such as kanamycin, streptomycin and neomycin as well as cell wall-derived peptides such as murein tripeptide). It transports substrate peptides of 2-5 amino acids with highest affinity for tripeptides. Also transports δ-aminolevulinic acid (ALA). [May be regulated by PTS Enzyme INtr-aspartokinase.] ATP-binding to OppDF may result in donation of peptide to OppBC and simultaneous release of OppA 96% 652.9
med BWI76_RS26865 dipeptide ABC transporter ATP-binding protein TM1750, component of Probable mannose/mannoside porter. Induced by beta-mannan (Conners et al., 2005). Regulated by mannose-responsive regulator manR (characterized) 47% 96% 307.4 dipeptide ABC transporter ATP binding subunit DppF (EC 7.4.2.9) 94% 638.3
med BWI76_RS16700 ABC transporter ATP-binding protein TM1750, component of Probable mannose/mannoside porter. Induced by beta-mannan (Conners et al., 2005). Regulated by mannose-responsive regulator manR (characterized) 45% 95% 287.7 AppF, component of 5-6 amino acyl oligopeptide transporter AppA-F 51% 334.3
med BWI76_RS07535 dipeptide/oligopeptide/nickel ABC transporter ATP-binding protein TM1750, component of Probable mannose/mannoside porter. Induced by beta-mannan (Conners et al., 2005). Regulated by mannose-responsive regulator manR (characterized) 43% 99% 271.9 TM1063, component of Probable rhamnose oligosaccharide porter. Induced by rhamnose 49% 301.2

About GapMind

Each pathway is defined by a set of rules based on individual steps or genes. Candidates for each step are identified by using ublast against a database of manually-curated proteins (most of which are experimentally characterized) or by using HMMer. Ublast hits may be split across two different proteins.

A candidate for a step is "high confidence" if either:

where "other" refers to the best ublast hit to a sequence that is not annotated as performing this step (and is not "ignored").

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. 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).
