HAMA reports Orn stems and Ser-Ala-Thr-Ala bridges.

Recorded evidence / 已记录证据 / Evidencia registrada

Mutanolysin-digest LC-MS/MS profiles include monomers and multimers.

Limitations / 局限 / Limitaciones

The proposed 3→3 crosslinks are inferred, not established enzyme activity. Preserve strain and subspecies labels; infantis is separately indexed. Bridge direction and individual peak structures still require figure-level curation.

HAMA 报道 Orn 肽干与 Ser-Ala-Thr-Ala 桥。

Recorded evidence / 已记录证据 / Evidencia registrada

mutanolysin 酶解 LC-MS/MS 图谱包含单体及多聚体。

Limitations / 局限 / Limitaciones

所提出的 3→3 交联属于推断，不是已验证酶活性。保留菌株、亚种信息；infantis 单独收录。桥方向和逐峰结构仍需图级核对。

HAMA describe tallos con Orn y puentes Ser-Ala-Thr-Ala.

Recorded evidence / 已记录证据 / Evidencia registrada

Los perfiles por LC-MS/MS tras mutanolisina incluyen monómeros y multímeros.

Limitations / 局限 / Limitaciones

Los enlaces 3→3 propuestos son inferencias, no actividad enzimática demostrada. Conservar cepa y subespecie; infantis se indexa aparte. Falta revisar la orientación del puente y cada pico.
