Pneumococcus · bridged
MurM adds Ser or Ala, then MurN adds Ala; FtsW–PBP2x / RodA–PBP2b build PG.
Atlas notes
- From Lys outward the bridge is Ser–Ala or Ala–Ala. Direct and bridged 4–3 links coexist. PcsB is not assigned a definite bond.
肺炎链球菌：带桥型
MurM先加Ser或Ala、MurN再加Ala；FtsW-PBP2x / RodA-PBP2b
图谱说明
- 这里从受体Lys向外画Ser→Ala；Ala→Ala也是常见支链。 无桥直接4→3与带桥型并存；不能把每个亚基画成带桥。 PcsB不强行标成已确定的内肽酶切点。
Neumococo · con puente
MurM añade Ser o Ala y MurN añade Ala; FtsW–PBP2x / RodA–PBP2b construyen PG.
Notas del atlas
- Desde Lys hacia fuera el puente es Ser–Ala o Ala–Ala. Coexisten enlaces 4–3 directos y con puente. PcsB no tiene un enlace definitivo asignado.
