Streptococci · Ala bridges

Mur/Fem-type branch assembly and PBP/SEDS systems; verify homologues by species.

Atlas notes

  • Ala2 is drawn. S. agalactiae can have Ser-containing bridges; S. mutans can have Ala2–3. Hydrolases are species-specific; PlyPy is a phage enzyme.

其他常见链球菌：Ala桥型

Mur/Fem类支链装配和PBP/SEDS系统；具体同源酶需逐菌种确认

图谱说明

  • 图示Ala2；无乳链球菌还可有含Ser桥，变异链球菌可见Ala2-3。 不是全部链球菌共用一套水解酶：CdhA、PcsB、GbpB分别保留。 PlyPy属于外源噬菌体酶，见外源酶页。

Ensamblaje de ramas tipo Mur/Fem y sistemas PBP/SEDS; verificar homólogos por especie.

Notas del atlas

  • Se dibuja Ala2. S. agalactiae puede contener Ser y S. mutans Ala2–3. Las hidrolasas son específicas de especie; PlyPy es una enzima fágica.
